If your camping will be more remote, than I'd say add more leveling blocks, especially for a longer unit. I carry 3 sets of stackers along with some wood blocks and that's been barely enough in some places like state parks. I added a storage box to the rear bumper just for blocks to keep from filling the pass-through compartment. The site we had last week took 7 layers under the left side wheels and the rear jacks where over a foot off the ground fully extended...looked almost like a mountain side mobile home park when all setup....
