OP update: I stayed with the Nitto Ridge Grapplers, but in the stock 275/70-18 size. Some of you may recall when I bought this truck it had these tires in 325/65-18 size, they looked badazz, and handled the camper well, but not what you want when towing heavy. These are stock 18x8 wheels. As an aside, the search function has a gap between 2020 and 2013 so I can't link to that post.
Anyway, $1431.08 out the door. *sigh*
Here's what the old tires looked like on the truck:
A good 5" wider than the stock size:
Buit since we don't camp on the beach anymore it's all good.
