Cool!
Whenever you can, post a photo with all the tools you have in that light brown bag. I'm pretty sure they are everything we need to dismount and mount back our trucks when we are on the road!

Yes, I think the tools that I have in the truck would allow me to do most work short of removing/replacing engine and transmission, and most of them fit inside the body panels.
The tool roll has (to the best of my recollection):
3/8-inch drive ratchet, 3-inch and 8-inch or so extensions
3/8-inch drive sockets from around 10-mm to 19, 22-mm for the shock nuts, I think 21-mm so I can use my torque wrench on the wheel lug nuts, the
5/8" spark plug socket. Mostly standard, not deep socket because I don't remember ever needing a deep socket, except for the spark plugs since I got the truck in 2012.
1/4-inch drive ratchet, 3-inch and 6-inch or so extensions,
1/4-inch drive sockets from 8-mm to 12-mm I think.
Combination wrenches from 10-mm to 19-mm
In bag, pliers, screwdrivers, wire cutter-stripper-crimper combo, 2 vise-grips, channel lock, offset philips, oil filter wrench, adjustable wrenches (both metric and english - LOL!), etc
I also normally bring my 30-watt soldering iron and supplies.
Inside driver side body panel, near the bottle jack, I have quart of engine oil, little brake fluid, hand cleaner, other cleaning stuff.
Old belts and hoses that I have replaced for spare (They're not bad but I replaced then since I don't know how old they were).
