Yes, they are bigger - 245/70R19.5 - Kelly KSR commercial tires. Great for a heavy load, not so great for my possibly too high truck lol.
The bed rail clearance is what I'm worried about. If I sit worse case at 57 inches, I'm not sure I'll manage to make it work with these tires. I'm hoping to ask the dealer to measure the fuzion today - level from ground to bottom of camper.
Any particular hitch help more? I'm looking to install a B&W turnover and companion. Pretty certain I'll need to two a gooseneck at some point...daughter rides ponies. :)
