The only mod I know that would get you 4" is to reverse flip the axles if they are on top the axle and you already stated you did not want to change the suspension. Personally I would not want to disassemble / reassemble the RV every time I went to use it.

To remove the obvious hassle of getting it into the building, I'd suggest to build a shed roof on one side of the barn and park the trailer underneath.
A guy always needs more storage space and I'd bet you will be moving stuff around, inside, just to park the trailer.
