Ok. So I have found 3 rims that are 16x7 from an old ford van in the junkyard. The tires on them are 245/75R16LT. The rims were $7.50 each and in good condition. I am assuming from the link that CapriRacer left that these are slightly wider that the rims currently on my RV. I jacked it up and removed one of the tires and put on one of the new rims I found. There seems to be no clearance issues and they fit nicely. Will a wider tire hurt anything? I'd assume it would be better because it could handle more weight...
If these will work I just need to find 2 more.
