Chris, I had to look several times to realise that was your truck, but I am very glad to hear you got away with no major injuries. Having seen it recently, I know you have put a lot of work into the truck so must be heart breaking for you.
Given the amount and nature of the kit you are carrying around, I would have thought a 110 commercial station wagon would suit you perfectly, but in the situation above I would suspect you would have come off a lot worse due to the lack of real structure above the waist line in a defender.
I hope the d3 driver gets his comeuppance, but don't let it eat you up, it's not worth it.
Have a good holiday
Mark
