Leveling TC

How many carry blocks or boards to level with. thanks

Depends on how un-level the truck and camper are.

Every parking spot is different. Every truck is different, and even more different depending on what camper is on it, how much water is in it, how much gear is in it, if there's a trailer attached to it or not, etc., etc., etc.

This is an impossible question to answer, because there's no answer that will be applicable to every situation.
