"Not yet mentioned is storage space and use of pallet racks. I have a tall garage and pallet racks on the back wall make great storage even for heavy stuff like engines and transmissions. Having a forklift to make good use of pallet racks is either yet another expense, a luxury, or necessity depending on your situation.
I'm considering rearranging things in my shop to use more pallet racks along one of the long walls keeping workbench space open under them instead of or in addition to racks on the back wall.
If you're planning on a lift that may or may not help with use of the floor space. I can fit (store) 3 or 4 trucks two wide by two deep in my long skinny garage now but probably only 2 end to end (with 3rd on lift) if/when I install a lift."
I don't think he had a warehouse in mind.
