Today I bodged together some jacks, using 4x4 posts. The rear ones just bolt in. The fronts have steel plates bolted to camper and 4x4. Oh wait, the truck is also 4x4! Yuk yuk. Seriously though, I jacked up one side of the truck, bolted on the camper brackets that side, the repeated the other side. Dropped the truck and the camper was in the air.
Inspected the Tacoma bed bolts and 4WC straps, had to tighten a little, reinstall camper with four new turnbuckles. One had bent and wasn’t holding the camper any more. No wonder it was rocking and rolling back there the last trip!
