Good boon-docking RV with good ground clearance?

Plan B RV, That is quite an undertaking! However, with the tires only 6” to 8” wide, it leaves a lot of unprotected area between and on the outside of the tries.... if you have a raised spot, or the tire drops into a hole or rut, you may still have contact at the camper rear. Hence the roller side to side, it will take care of any high or low!
