Ok guys need your help!

The hoist in the bed sound sketchy. Another idea.... if you can tear up the ground/grass, just get a coupla 4x4's, bevel one end on each and connect a chain to them with some boards spacing them apart to make a skid, drop the k-member onto the homemade skid, chain it on or a coupla bolts through the k, and just drag it.

If your truck is 2WD and your going across the grass, you might be challenged with anything but a dolly.
