This is, probably, how a short trailer with some limited left-right movement will behave

Both MAN and Renault are offering hidraulic driven front axles in their range.

Yes, special and rare landys should be maintained as original as possible, for the future generations. When you mentioned the Series I LWB as the ideal chassis for a 6x6 conversion I said: "Oh yes, I have one of those". Will I use it for a 6x6 conversion? Certainly not, it´s a very rare hearse conversion that will be restored to it´s former glory. BTW it can be cosidered a family heirloom, as both grandpa and grandma used it in their last terrenial journey. I have searched unsuccesfully for the exact ESARCO LT230 arrangement. Does anybody know how this one ended? http://forums.lr4x4.com/index.php?showtopic=16500&hl=%2Besarco+%2B8x8+%2Boil#entry169273

http://forums.lr4x4.com/index.php?showtopic=71288&hl= viking winch&page=3 Bill, was this 90 6x6 ever built?

I will talk with my brother. He has both a short rear overhang SANTANA 2.500DC and a Land Rover axle based trailer (in fact, the remains of Seferino, our beloved 88" SIIIA). Both vehicles are no longer road-legal and will make a good testbench for the powered trailer idea, beeing budget, and not the laws, the only limitation. The design could be tested in rough terrain at our parents properety. If we create a good design we will try to replicate it with the Disco and make it road legal.

Does anyone know the equivalent EC regulation for this?

The famous Perentie. Mi mind switched to "german" as soon a I read Gwagen. Thats why I got puzzled with that 6x6 german army LR that my mind created in a fraction of a second LOL

"Australian army". I dont know why I read "german"

Muddy, I have also worked with tractors and in various workshops, including a JD franchised one. We made propshafts to order and also off-the-shelf ones, wich carried a warning label reading "max 3000rpm". In the worst case, according to my calculations, with 4,75 ratio and 29" tyres, 3000rpm at the pinion will give 87km/h. Bill, I never heard about german army 6x6 LR.

Farm tractors use that system, even in powered trailers, and seem to cope well. There is a farm machinery breaker near home that will provide secondhand parts at reasonable prices. Only problem with farm machinery parts is that they are rated to a maximum of 3000rpm. I will calculate diff pinion rpm vs 90km/h (max speed in Spain for 750kg trailer) with various ratios/tyres to see if it could work. Chains will limit trailer movement to stay within UJ´s limits.

Interesting trailer. Could be an option for hinged/twisting chassis, with the advantage of beeing removable. If made light (less than 750kg) it could be done without any type of brakes, keeping costs to minimum. http://www.scale4x4rc.org/forums/showthread.php?t=41922 It´s coupling will be difficult to make legal Alternatively this arrangement, with standard type tow pack, could work. Some chains (compulsory in no-braked trailers) will limit left-rigth movement and thus avoiding the oversteering seen on 101 protos. This will only work with a landy with extremly short rear overhang and trailer with extremly short tow hitch, creating a car-trailer wheelbase similar to that on a 6x6.

Thanks for the link!

This is Google Images´ answer to "pivoting chassis"

Unfortunately Google is not very cooperative today. Have not found any SimonR Buggy. Twisting Buggy showed this

Berliet VPH 6x6 from 1932-36. Bogie suspension betwen axles 2 and 3. Steering in axles 1 and 3. Only two protos made ever. No series due to it´s complexity

Excellent source of ideas http://www.unusuallocomotion.com/

Thank Dieseldog! Just an idea for a prototype... Independent suspension has many advantages, but wheel travel is certailny not one of them. How could this be improved? Think about this design... ...attached to a twisting chassis, as used in compact articulated farm tractors... The chassis will provide the travel that the suspension itself is not capable of delivering. Chassis could be lockable for road use. Chassis' will need to rotate concentric to propshafts, like the TATRA design. For even greater articulation the chassis could also be capable of up-down movement, as seen in MB Hexawheel design proposal. Here an articulated prototype from 1955 (Dodge WM300)

I have just located my copy of the book "Land Rover Series II 1958-1971" by Brooklands Books ISBN 0 948207 98 1. This book was extremly important for me. It was 1997, I was a 17 years old teen with Land Rover madness and mine was the only case in the area. Land Rover´s 50th anniversary was nearly there and I went to a classic and oldtimer car gathering. There I found lots of memorabilia of LR, and there it was, a book that showed me that Land Rover madness was spreaded all over the world and that I was not alone. In this book there was also an ad from Land Rover Owner International magazine. Of course I sent the subscription application. That greatly improved my english level, and one year later I obtained my First Certificate in English from Cambridge University. I took the book to a print shop and they made for me a series of posters in A3 size of Bill´s 6x6 climbing over a fallen tree for decorating my bedroom. Here just some pics to complete those posted by Dirtydiesel

After eight pages of discussion and great feedback from the LR4x4 community I have (nearly) abandoned the idea of making a 6x6. Legality, budget and bulding skills I don´t have, along with the fact that 6x6 is not neccesary better than 4x4, had showed me that a good 4x4 will fullfill nearly all my needs: a capable offroader suitable for daily driving arround city. Standard tyre size belly axle has appealed me a lot. It will be cheap and simple and will give the vehicle nearly same trench-crossing ability of a propper 6x6. Powered pitch-roll trailer will also be relatively easy to build/register (under 750kg GVW trailers don´t need MoT test, insurance or number plate) and will be usefull for hollidays and firewood collecting arround farmhouse. Let´s face it, at best, trailer will be used 4 or 5 weeks per year. Only thing that I will have not solved will be the excessive turning radius the car has. I should have a look at those post about steering geometry and Akermann angles, as this could help. Dieseldog, what´s the meaning of "COC"? I have been thinking that if I maintain 205R16 for city use I could save the roof conversion. Even a 2.1m tall the car will pass under the bridge at it´s tallest point.

About Lambo Doors, I could see between door and A pillar Of course at very low speeds. I don´t consider practical making bespoke sliding glass for it. A broken glass will have no other solution than making another bespoke one. Forget about off-the -shelf parts. Series ones will be illeagal as they don´t have post ´82 "E" marking.

As Bill said, belly axle should be located above chassis. This could lead to the necessity of lowering engine+gbox (=better propshaft angles but less clearance with obstacles) and a body lift for clearance between body and new axle. It´s not a Disco chassis, it´s a 70s Rangie, but you get the idea

Bill´s LR http://forums.lr4x4.com/index.php?showtopic=6428 I have been consulting both spanish and european regulations, and I could make ANY moddiffication to a vehicle and register it as PROTOTYPE. Unfortunately I will need to be a "BUILDER" (how is that achieved?) and the car will be road legal for a short period of time, just for testing before "production" starts. In my area there are quite a lot of blacksmiths that are approved saloon car and farm tractor trailer builders. I have contacted the one that 15 years ago made my fathers trailer out of a Fiat Panda scrapyard axle. For little money he will give a VIN and Logbook to a homemade trailer, as soon as it is sized as one of his "production" models. So, I could make a trailer with collapsable hitch and LR axle that will move up-down, but no left right, and also cappable of tilting. When used with the Disco it will a kind of GammaGoat/MB Hexawheel. Traction will be delivered via a farm tractor max 3000rpm propsahft from rear axle with freewheeling hubs on axle. Belly axle will be driven with belts/pulleys from LT230´s brake drum. RRC low roof conversion and rear end will give height clearance and enchance better trailer/LR articulation. Chopped Disco + mini trailer will have a length of about 480cm, beeing able to use multi lot parkings with a deployable camping shelter on it. A mini version of this will be used with the trailer on hollidays.

Does anyone know how much shorter is a "Wolf" short nose diff when compared with a Rover one? And length of a ZF 4HP22/24 and Chrysler Torque Flight A727? Will such a manual-auto combo work OK when reverse is selected in the manual one? I have thought that a ZF auto will be easier to obtain ant it´s overdrive 4th could favour the use of super tiny 205/50R16 road tyres for city use, avoiding RRC roof conversion.

Is it a Nissan Terrano based one? In Spain "Maverick" was a rebadged Nissan Terrano II (made at the Nissan factory in Barcelona), but in some RHD markets, like Australia, "Maverick" name was used in rebadged "Patrol GR" (well, "GR" in Spain, over there I think they call it "GQ").
