It sounds like you have a set of the Ultra-Fab Rotating Hitch Mounted Skid Wheels # UF48-979014.

These are supplied with straight carriage bolts, not u-bolts, for installation. U-bolts might distort the bracket that is attached to the caster. My contact at Ultra-Fab said that for this item you can use Grade 5 (USA) or Grade 8 (China) hardware of the appropriate length for your application, but not u-bolts. Other Ultra-Fab skid wheels, such as their # UF48-979018 do use u-bolts for installation.

Generally an RV bumper is designed to take lateral force but not the vertical force it would encounter from having skid wheels installed on it. The RV frame at the rear (near the bumper) is the best place to mount skid wheels. If there is a hitch on…
