I forgot the corkscrew on one trip and it took me 15 minutes to find another camper that had one. It was the longest 15 minutes of the trip for my 2 adult daughters. They never let me forget it.

Bottle opener, and cork screw.

A good AC/DC clampon ammeter and knowing how to use it. This one offers a lot of function.

I take lots of stuff , way to much but you never know when it'll be needed .

I didn't realize how much I needed a combination power tool set until I got one for a repair project. I have used the power tools many times since and would not travel without one.

From Home Depot I bought a Black & Decker 18 volt cordless power tool set. It includes: a circular & reciprocating saw, a handheld vacuum, drill and high powered flashlight. All of this comes in a nice canvas carry bag.

Also I purchased a 150 piece channel lock hand tool set that comes in a plastic fold open case. Each tool has a marked spot in the case so it's easy to see when a tool is missing when your cleaning up after doing some work. It's has standard and metric sockets and wrenches along with ratchets drivers and various bits like allen, star, torx, screwdriver...etc

A lot depends on your abilities. I pack a meter to diagnose electrical issues. I also took everything I needed to change any hose or belt. I kept a ScanGauge to diagnose any abnormal codes that might be in memory during an engine malfunction.
I also carried a grease gun so that I could crawl under and grease the chassis on a regular basis as we traveled. Grease is cheaper than parts and I usually never went longer than 1000 miles between greasing the chassis. It also gave me a chance to look underneath the chassis for any problems. I carried several of the extra large white disposable suits used by painters, etc. The are available at Home Depot for a few bucks and they slip on over your regular clothes if you plan on getting dirty. A lot also depends on where you travel. Walmart and their tools are never too far away, as well as hardware and auto parts stores.
