I ditched the heavy flite box a long time ago and bought a couple of the nylon tool bags you can get at Home Depot and the like. I carry all the tools I need for basic maint at the field. I also made a simple caddy for my fuel bottle( I fly gas) and use a 12v lipo to power the pump. I also converted my starter to run on a 4 cell lipo and carry that strapped to the fuel caddy. There are adjustable height work stands out there just google it. Sorry to here about your recent disability, but applaud your determination not to slow you down.
