I keep finding new uses for my hydraulic lift, roll-around shop cart. Discount tool outlets sell them.
Heavy items in your pickup truck can be slid onto it at tailgate height, rolled elsewhere, and then eased almost to the ground where you can deal with it. Or reverse that process to load your truck.
If you have a portable vise, you can stabilize it on your cart table, clamp your workpiece, and adjust the height to comfortably drill it, grind it, paint it...
It can be an improvised table extension for cutting long pieces, or as an outfeed table. Matching the heights is easy. Matching higher table heights, like my radial arm saw, requires some blocks on the cart table.
Amazing deals on this 500Lb Hydraulic Table Cart at Harbor Freight. Quality tools & low prices.
