Thank you Fred. I found your post about the axle swap last night and I read through it. I think it's something I can handle. These campers are fine with 15 inch rear, and 14 inch front wheels right? I assume the different size tires offset and make them a similar rotational size, anyway. Do all the GM 8 lug 15-inch wheels have the same offset? Or do I need to be careful which Wheels I get also?
