4 wheel drive class c

im kinda committed to the rig i just got done making payments on. one trip to yellowstone and two smaller trips to the anderondiks{however u spell that} and the smokies then getting ready for glacier opened up a corner with a bulge and out fell a five gallon bucket of rotten luane, oh well , just have to fix it but thought about fwd and one of ujoints do it yourself kits would do right by me but am just concerned about putting all of that money and work into convrerting it and then finding out i cant get it inspected. Va, just out of curiosity is your rig a 450 chassis?
