bikepsyche: that's what I do. In fact when I'd put the camper on (and I haven't set my resto-mod on the truck this way yet, this was with my previous pop-up camper), I'd leave the rears loose enough to wiggle until I feel I've "set" the camper into the front bed bar and centering points by bouncing a bit down our gravel neighborhood road, maybe a little brake. Then I'll re-set the fronts to the quarter inch tightening thing (instructions) and finally tighten the rears until hand tight, just taking out the wiggle. I had that on some off-kilter and even today, I went out to check "the ears" on mine (and maybe a Dodge bed is different than some others) but my ears are well away from the bed metal and everything looks so good, no evidence of body bending and all the parts looks real good. Installed in 2006. (Shrug).
