the softer/weaker manufactures make a camper's frame, the more stabilizers become necessary .... with a few exceptions, the old school days of heavy rigid/strong frames is all but a thing of the past .... the same can be seen in the growing number of campers for which 4 point auto leveling systems can't provide sufficient support so they require 6 point leveling systems .... based on use by some of the folks we camp with, JT's strong arm system is a pretty good one
