I’ve made the 1000 mile round trip up there in my F550 several times, and even with a bed, you get a pretty good jarring. You have my sympathies doing that without a bed.I twice had the "privilege" of driving new F550 ext-cab 4x4 cab and chassis from OKC to Harper, KS. Needed two days off and bruised kidney therapy both times afterwards lol. Even let most of the air out of the duals.
