The one tool that gets stored in the side compartment is:
Goodyear 24V battery powered Impact wrench
I use it each trip to power the stabilizing jacks down and back up...
It's right there if I need it to remove a tire/wheel on the AS or the TV if needed...really handy for that.
This tool is really handy for any of those jobs with rusty, frozen bolts/nuts...used it when changing axles recently, really a time and knuckle saver...
I have a hand cranked blender...maybe I could remove the handle and use the Impact to make Margaritas...
