[neverfinished]

I've used a pair of jacks, 4x4 posts and saw horses to remove a bed. I unbolted everything, positioned the jacks inside the frame rail and as close to one of the front bed supports as I could get using blocks to get the jacks high enough to reach the bed. I put a 2x4 across the tops of the jacks and lifted them in unison. Once I had the front of the bed high enough I slid a 4x4 post under the bed and up on a pair of saw horses. Repeat for the rear and then drive the truck out from under the bed.
