Sun Tzu's Revenge

I think that Sun Tzu said something like "No plan survives contact with the enemy".

That's what it feels like at times. Careful inspection of the chassis revealed no suitable way of getting the front mount down near the centreline. This is necessary for the four point mounting to operate properly. So back to the three point mounting. With this one there is not as much need to have the centreline of the mounts on the same axis as the twisting occurs. Desirable but not as critical - especially with the type of hardware selected as it has some compliance in all axes.














Trial mounting of (unfinished) mounts to make sure everything can actually be attached in that position. Front longitudinal mount about 450mm behind front edge of accomodation unit intended position.















Rear transverse mountings (also unfinished) in approximate position. The blue beam indicates how far the acomodation unit will overhang the end of the chassis.

Hi to everyone. Thanks for your positive comments.

Mini Track Loader : I'm not sure which part you are referring to. (If it's) The three point mounting system it is part of the DPI/VSB ("government") recommendations. It is used extensively by people who build "Expedition Campers" eg UNICAT and is even supplied on a Mercedes UNIMOG as standard. I first set out to learn about it when I discovered (especially 4wd) truck chassis are MEANT to twist. If you build anything rigid on one expect it to break eventually.
