Aside from all the usual stuff, I stumbled onto one very useful shop item- a wheeled, hydraulic lift table that is infinitely adjustable, height wise, with its foot pump. Things that I've used it for so far:
Back your pickup up to the garage, slide your load onto the table, set at tailgate height, and roll the load over to wherever you want to work on it.
Use the table as an extended work support, setting its height to match the main table you are working on. For example, supporting a long piece steel at the height of your chop saw. If the main table is higher than the max height of the hydraulic table, use some 4x4 as shims.
Set the height of the table so that your workpiece on it is at a comfortable working height.
As above, but set a heavy vise on the table to clamp the workpiece. I've done this for holding a piece to be welded at a comfortable height. The vise can be set on the table without bolting it down if it's heavy and there's not much side force involved.
Plus, it's a handy surface on rollers, even if you don't need the lift.
This looks similar to the one I bought from a roving semi truck tool show. Mine leaks down eventually but the frame can be blocked at a certain height with the proper length of wood:
