How to Lift topper off truck?
Lifting a topper of a truck is usually an easy job but it helps
to have two people. First, remove the clamps or tiedowns on the
inside of the bed of the truck. Next, lift the topper from the
inside and shift it slightly to one side or the other and slightly
to the rear. Finally, have two people grip the sides of the topper
and walk it back off the truck.
