Loading the Beds

The 39 Dodge bed, 36 Chevy bed, and the trailer box needed to go to the desert. So ...
You load the smaller beds on the big bed.
Lift the beds in the air.

A little more height and the trailer starts to slide under.

Oh but make sure the bottom of the trailer is loaded first.

Grab the engine hoist to make sure the back stays stable.
Use pipe rollers to roll the bed into the trailer

So a floor jack, an engine hoist, a LOT of dunnage,
a little ingenuity, and a days work and the beds are safely loaded.
