I am afraid that my HILO trailer is lacking the structural integrity to deal with the torsional stresses and want to isolate it from them as much as possible.
I am still waffling on the final frame design but will need to decide soon as I am approaching that phase of the project. I think I will be solid mounting a significant subframe and then doing a three point mount from that to the trailer frame. This trailer really compresses in height so I have a lot of space to work with. I will be able to mount it quite high and still have the top below cab level. It looks like I have about 16" to work with between the truck frame(lower section) and the camper frame. I am hoping to have a compartment that goes the full width of the truck between the fuso frame and the camper in the center of the wheelbase that will fit two 37" spare tires side by side. I feel the benefits of having them out of sight and having the weight centered in the wheelbase are worth the extra effort.
