I am pretty sure the wallboard will crack on the road. usually 1/4" (or metric equivalent) plywood is used for wall coverings.
for fire protection, perhaps a sheet of aluminum on the "toy" side. that will really just depend on how big a fire, as to how long it will hold up, burn-time.
as for steel studs, my concern would be the joints, under road travel. perhaps the wall-covering will hold the joints together.
i am fortunate that the aluminum frame outer walls of my camper are in good shape, so i can build off of them.
as for transit weight, you need to know what actual axles are rated for. mine, a 25' 5th wheel, has 3500 pound axels, giving me a total weight limit of 7000 pounds. so at no time, should this trailer be loaded with more than that, including all framing, walls, cabinetry, etc... and the balance needs to be considered. to much weight forward or rear of the axles can lead to loss of control on the road.
this would be my best thoughts on the matter.
