@Darwin and Carl - Sorry for the delayed response, I have been in the working vortex of life recently. Am getting ready to make our annual Fall pilgrimage through the Tetons, Yellowstone, Beartooth Hwy, and Glacier NP.
I haven't driven the truck much since installing the flares, but they seem to work just fine.
Darwin - the camper is awesome. We really like the space, storage, full bath, and solar option. We have removed the A/C and microwave, as we won't use them (we are seldom near power). The fresh water tank is on the small side, so we carry extra water in the generator compartment (another item we don't need). This is a great camper and I would encourage you to talk to Rex at Northstar.
