Mine did this on the motorway at 70MPH, no warning, no vibration and as far as I know the pressures were fine up until that point. Inside side wall was completely fine, not a mark on it. I'd been told by an Australian that these tyres had some issues with structural failure but assumed it was an extreme heat issue or something and dismissed it. This was one of a pair I bought in 2016 to replace the 4 year old ones that I'd driven around Australia. I've lost all trust in these tyres as a result and have replaced them all with a different make. I've had tyres give up on me in the past due to punctures but never had one like this where the sidewall split around the entire circumference and have lost all confidence in them as a result. I'd be concerned that any sign of cracking, especially on the outer sidewall, might be a sign that a similar structural failure is occurring, if that's what happened to mine.

Yes, built it myself, more or less. The two main components that determined the design were the trailer itself and the tent. The tent specifications give you the optimum height above the ground for the tent to be mounted so that determined how high the supporting structure needed to be. Original trailer... Tubular framework made and treated... the 3 longitudinal bars that support the tent bolt on so the canvas can be below them but above the main frame. The canvas fitted (custom made by a local company) Interior electrics fitted out, consumer unit, charger and two large batteries, waterproof mains sockets at each side, accessible from the front and sides. Initial water pump on wheel arch - later replaced with a better unit. LED lighting strips attached to each of the roof bars. I also added a wooden "shelf" around the entire tub top to make it easier to add/fix things into place and run wiring etc... Rubber matting on the floor... Simple water system with individual bottles to make it easier to fill and avoid contamination... Fridge fitted... (added a home made fridge slider later on)... fold down water tap at rear (there's one on each side), gas bottle in situ. One of the best things about the tent is that everything for the tent goes in the bag on the top of the trailer so there's loads of room inside the trailer for food, cooking gear, clothing and so on. Internal view, main double bed upstairs... (mattress permanently stored in the tent as per a roof tent) there's also a zipped access panel that lets you get access into the side of the trailer from the accommodation. Additional annex room has a curtain and is large enough for a double bed (we use it for dog crates !) You can deploy the tent with or without all of the extra bits depending on how long you expect to stay, for an overnight we wouldn't put up the annexe or most of the side awnings, they're all detachable.

Probably the easiest way of fitting a NATO to a TD5 rear cross member is by using a 2 inch receiver because that will use all the available tow bar mounting pick up points. It does mean that the NATO mount ends up lower than a direct mount would be tough. That's what I used on mine although my chassis was aftermarket and didn't have the captive nuts so I also added a 6mm spreader plate with captive nuts behind the cross member. I only tow a Sankey with mine so having the NATO a bit lower than intended with +2 inch suspension on the 90 means it tows really nicely as they seem to like to be a bit nose down.

I've been a Weller "fan" ever since I started soldering, about 50 years ago, scarily ! A couple of years ago though I started to find myself dealing more and more with SMT stuff and struggling with my old school setup, so decided to try out a soldering station. As it was only really an experiment and I still had the trusty Weller to fall back on I went for a cheap 2 in 1 soldering station like this one... https://www.ebay.co.uk/itm/384460906311?hash=item5983a7df47:g:MiQAAOSwuxRhS-OQ At that price, I'll be honest, I wasn't expecting much BUT I don't think I've used my old Weller since this arrived. It's been really good, the iron heats up quickly and has a "sleep" mode so the it detects it's been in the holder for a while it reduces the temperature to save the bit. The selection of bits that came with it are a good selection from the very finest needle bit to a large flat bit, all of which have been fine and changing bits is quick and easy. The hot air gun is also a real bonus, as well as easily replacing SMT ICs and discrete components it's great for heat shrink too and, again, the range of nozzles for the gun mean that the heat is very localised. I was replacing some 8 pin SMT ICs on some boards last week (Cheap Chinese CAN BUS boards that didn't work due to the dodgy ICs fitted that I replaced with genuine items), the ICs are surrounded by discrete components but I manage to replace the ICs on all 5 boards without disturbing any of the surrounding components. As I said, for £60 I wasn't expecting much but I've been very impressed with it.

I've experienced this kind of death wobble many times on mine, normally indicates that one of the TRE's has some play in it. Once it starts the only way to stop it is to come to a standstill, very scary sometimes. It seems you've checked the normal stuff though. However, I did have the same issue many years ago on a Range Rover Classic with road tyres on and it took about 6 months to diagnose. Everything was tried, damper changed, everything adjusted/tightened, checked etc... Turned out to be the tyres, changing front to back made no difference but borrowed a mates wheels and tyres and no sign of the problem. New tyres fitted to the original wheels and the problem went away. There was nothing visibly wrong with the tyres and the only conclusion was that the tyres were distorting and took a while to return to normal again. We figured out it always happened after a bump in the road, even the tiniest pothole would set it off, even running over a cats eye. If I were you I'd borrow a set of wheels/tyres and see - if nothing else it rules the wheels/tyres in/out as the cause of the problem.

Ours is Oslo Blue, looks pretty much the same colour...

MS is still a good option and people are doing a lot with the built in CAN comms these days which wouldn't take a lot of work to bridge to a gearbox controller, even if you had to covert MS CAN signals into different ones using an Arduino or similar. I've just built something similar for my van using an ESP32 to bridge CAN devices and broadcast the CAN data on Bluetooth so I can view it on my phone. ESP32 has a built in CAN controller, WiFi, BLE and costs around £3 each from China ! That said, MS is not what it used to be either in support or ethos. The original spirit of open source collaboration which resulted in hardware, firmware and software advances got lost somewhere along the way with commercial offerings taking precedence and costs increasing despite costs of manufacture and components reducing. The MS forums are dead so support is nowhere near as good as it used to be although we do still have good resources for it here. Speeduino is probably the current equivalent of where MS used to be in terms of having an active community and open source development, I'm looking to replace the MS on my LS with a Speeduino at some point simply because it's cheaper than an MS upgrade (I'm still running MS1), faster and more flexible. I'll also be looking at controlling the gearbox with it. The Speeduino forums are still active, you have a choice of processors, the firmware is written in a modern(ish) language and there's even documentation to help developers customise the firmware ! I honestly think that, these days, Speeduino is the community built, open source engine and gearbox control system. MS is now very much a commercial offering with high costs which means it needs to be compared, both by feature and price with other commercial offerings and it pretty much falls down when compared to other commercial system. Having closed firmware isn't an issue as long as it works and you can get access to it for diagnostics and tuning/adjustment.

On a 3.5 Flapper EFi ? Do you mean the extra air valve ?

I'd not long since joined the motorway, having negotiated 3 roundabouts and a tight left turn onto the slip road followed by a relatively sharp left hand bend at 60-70 on the merge onto the motorway from a dual carriageway. No understeer, no handling issues. Whatever happened it happened in the 2 miles after I joined the motorway. I also changed lanes several times as I was overtaking slower vehicles and pulling back into the inside lane and no signs of understeer or pulling to one side. Up until it let go there was no indication at all that there was anything wrong. The inner bead, tyre wall and tread are completely unmarked/unharmed. I guess I'll never know for certain but the front left tyre (same age as the front right) isn't going back on again. Someone did warn me that they'd seen issues with these tyres and the sidewalls failing but the ones on the rear (rotated from the front) are probably 4 years older and have had a much harder life having been on when we drove around Australia. Maybe a slow puncture that led to the tyre overheating, maybe a structural failure, maybe something on the carriageway that cut it, who knows. On the plus side, nobody was hurt, I didn't spread large chunks of tyre all over the motorway and I got home safely on the spare which is from the same batch as the rears. I now have mud tyres on the front and ATs on the rear while I figure out if I should buy some more of the same make or move to something different. Seems like GoodYear might not be a good candidate

Typical really given that this topic is under discussion... Had I not had a spare with me on Sunday myself and my dog would have been stranded at the side of the A1M after the OSF tyre sidewall seems to have disintegrated. No idea what caused it as the tyre is only a couple of years old. The inner wall was undamaged, the outer bead is undamaged but the wall has split from the tread. 70MPH on the A1M, no warning, no vibrations before it went. With the spare and the means of changing it we were probably only on the hard shoulder for around 10 mins. Probably not repairable with sticky string...

Fuel pump problem I'd expect. It's a two part pump unit, low pressure and high pressure. It'll run quite happily up to a point off the low pressure pump but will top out and be unable to rev high for any sustained period. Often you can hear the pump isn't well when you switch the ignition on before starting. If you keep it at low revs it'll run quite happily but as soon as you apply any load and/or higher revs it'll have no power.

Permanent relocation or temporary ? If it's permanent you might be eligible for a personal import as long as you can meet the criteria. You need to have a visa that entitles you to apply for citizenship for a personal import to apply, you also need to have proof of ownership and use of the vehicle for at least 12 months prior. There are also options is the vehicle is over 25 years old. You really don't want to have to pay import duty as that can be as much as the value of the vehicle or even more ! The age of the vehicle can also make a difference, as can the state that you want to enter and register the vehicle in. NSW, for example, tend to be a lot more flexible than WA so shipping into Perth is more complicated than shipping into Sydney. As for shipping, that's relatively easy but costs of containers are very high at the moment due to COVID, I wouldn't be at all surprised to see it costing 7k plus for a one way shipment at the moment. You might want to consider if your Land Rover is special enough to you to warrant the cost of shipping - you can pick up second hand Defenders in Australia fairly easily and they tend to have a lot less corrosion that UK examples ! You might also want to look at cost of ownership out there, depending on where you live, you might find getting hold of spares or a mechanic that has any experience of them can be difficult especially the further north and west you are. If you haven't done so already, join the AULRO forum.

The ECU can easily be changed from Discovery to Defender by anyone with a Testbook or equivalent (did mine with an Autologic one). Only takes a few minutes, just remember to take a note of the injector codes before you start although, that said, it would be worth checking those against the engine anyway. I'd assume that anyone that didn't bother changing the vehicle type on the ECU probably didn't bother coding in the injectors either...

It's definitely worth trying a different set of wheels/tyres if you can. I spent months trying to find a similar issue on a Range Rover classic that would start to oscillate really badly after hitting any kind of bump at speed. In my case it was the tyres that were at fault although there was no visible sign of a problem. Wheel spacers can also hide problems so removing them from the equation is definitely a good idea.
