I once had a crock pot who had "keep warm" setting where you would expect the HIGH setting to be. I had to keep a post a note inside to remind me. I can't tell you how many times I had a similar experience until I started using those notes.
Have you considered a truck camper? The ones being built today are very different than the ones what were on the road when I was a kid. If you plan on doing a lot of traveling they are wonderful! You can park just about anywhere! Their size makes going to hidden sites pretty easy. If you drop the camper you can use the truck as a vehicle for sightseeing. Ours has a slide out and I find that with the camper storage and the back seat of the truck. I have room for everything I need. The truck camper is not as good for long term camping. A rainy weekend can be a little claustrophobic. If you go to a RV show be sure to look at truck campers. I think you'll be surprised!
