+1 on what Frits said about drones, Drew. A few years ago when I was shopping, DJI was one of the few that offered hands off hovering (some call it automatic place keeping). It was very comforting to know that letting go of the controls would stop the drone from doing whatever it was about to do. It also offers a return to home feature, where it will ascend to a safe altitude, transit to the launch location, and automatically land. Combined with a good camera that takes both stills and video, it was able to do everything I wanted, with not a lot of me worrying about losing a fairly expensive piece of equipment. More adventurous folks actually pilot theirs, and even race them. Me, I just get it off the ground and up into the air high enough to avoid running into anything, then fly over whatever I'm interested in videoing or photographing. Then see if I can make it back to the launch point before the fifteen-minute battery runs down. The model I ended up with is the original Mini. There have been several generations since, so maybe you could pick up a used one at a significant discount from somebody that's moving to something more sophisticated.
Lots of folks carry an old Honda Trail 90 on the bumper of their RVs. Small, light, very reliable. Honda even makes a modern version that's worth taking a look at. Not sure they're light enough to lift onto a rack, but you can find bumper hitch racks that tilt that are pretty easy to load. I use one for a 300 lb. Yamaha, and it's a real handful, but the little Honda would be a breeze.
I rode an e-bike once, a rented one, around Santa Barbara for an afternoon. It was light enough I could pedal it if I had to, heavy enough I was glad for the e-assist, particularly when going up hill. I could probably heft it into the back of a pickup or onto a carrier, but wouldn't want to do that often. Again, the technology is evolving rapidly, and there likely a ton of them available used that don't have the latest-and-greatest, but that would be perfect for putting around the campground or a quick trip to the grocery or nearby restaurant.
Good luck in your search.
