I got an idea, maybe some kind of short ratchet strap might help stabalize larger items,Not knowing your setup,maybe some eye bolts or hooks in the floor or on a heavy bench,might get ya able to put more leverage when ya need it.Maybe a couple differnt power drills, and several differnt size of exstentions,might help reach tough locations. Also some kinda rolling cart,either to be able to move tools to an item,or move an item to the tools. having good decent screwdrivers will help, dont want them stripping or slipping.could get ya off balance, frustrated or both.Hope some of this helps.
