For a 2WD 2018 Ford E-350 Class C cutaway chassis I recommend the SuperSprings rear axle kit # SSR-130-54 which is rated for 2800-lbs. Kit # SSR-106-47-1 will be too stiff.

Since a flat towed vehicle does not really load tongue weight on the Thor's hitch the way a trailer does the kit # SSR-130-54 will correct for most of the sag without making the ride too hard. I ran this thinking past my tech contact at SuperSprings and he agreed. For a front axle kit he suggested # SSF-106-40.
