Even better tip. Use a Engine Hoist when you don't have help. I stopped struggling and use tools with out breaking the back.PSA: Whenever you need to lift heavy and awkward objects like your bumper, always use your lower back and use snatching and twisting motions as you swing upward for best leverage.
Truck looks great, have fun unplugging in the forest.
if no cherry picker is available.... maybe a come-along, ratchet strap or some sort of pulley system to your rafters might work as well. anything beats dead lifting that thing!
