Heres the list I ended up with...
The Kit for the Motorhome is larger and pretty much medical only and has Sam splints, Celox, and even a suture kit... Way overkill for sure.
The kit for the RZR is smaller.
This is what I ended up to keep in my vehicles.
I added a few things for a kinda survival or stuck somewhere kit as well as 1st aid needs.
Much better than any pre- made kit I could find.
I used smaller 20mm ammo cans, 14"long 9" wide and 4" tall. It fits nicely under the rear seat of the truck and under the passenger seat of the Subaru.
They are also very tough and water/air tight.

6 Alcohol wipes.
2 Triangle Bandage with safety pins.
10 1" bandaids.
6 Butterfly closures.
5 Super glue packs. liquid stiches.

6 3x4 sterile bandage.
2 8x10 abdominal pads.
1 1" roll surgical tape.
2 instant cold packs 5x5.
6 pr nitrile gloves.
6 burn crème gel.
6 bacitrine gel

8 emergency drinking water bags. 2 day supply for 1 person.

I think that's all of it...lol
Its a bit overboard but once I had the box picked out I figured I might as well fill it up.
With any luck I wont even need to open them up but if I do more stuff has got to be better...
