Makes you wonder why anyone considering mounting a camper on a Fuso would even consider fish plates or U bolts, doesn't it?
Westyss' camper is a perfect example of how much these chassis can flex.
WHOA! that looks to be a really stuck truck there, my worst nightmare is to be that deep in muck, and it looks to me like all they used to get outa there was a shovel and throwing whatever under the tires.......... how long did it take to get it out of there?
just because the fuso frame can flex so much doesnt mean it was designed too over and over. my take, mount solid with alittle cushion between the camper frame and camper box and let the suspension (hopefully with simple leaf spring and shock upgrade) do the work.
I second that, this amount of constant flex will break the chassis, soft mounts are the answer as used by just about all, earthcruiser, ATW etc
I want to make sure I understand. You are suggesting mounting the box tighter to the frame which will limit frame flex (because of box rigidity) and force the suspension to do more of the work? Assuming the answer is yes at what point does the box become over stressed and what safeguards are in place to prevent this? Construction strength? Common sense? Experience?
I have seen pictures of box mounting "clips" that are bolts with springs that appear designed to isolate the box from frame movement as much as possible. Where can I learn more and see pictures of these "soft mounts"?
