I keep a cheap moving blanket and a large tarp. The former is great if you need to go under the truck or camper for any reason. The latter, with some bungee cords, can stop a leak temporarily during a rain - then once the rain stops, you can do a quick repair.
I had my clipper established with a lot of tools, etc. When I got it back after being stolen, everything was gone. So I had to restock it. I got an inexpensive standard tool kit with screwdrivers, pliers, etc. I added a kit with various screws, bolts, and nuts. Multimeter. Fuses.
