These are from a prior pop-up and present A-frame owner:
- safety: rubber chocks, not plastic ones. I've had the plastic ones skid on the ground, and not stay tight. I've also had the plastic chocks literally blow away in Wyoming winds. Harbor Freight has the nice rubber ones on sale for $5 each with a coupon.
1) battery shut-off switch to disconnect all loads. Unless you store with the PUP plugged in, you need to disconnect the battery from the camper. Otherwise, the battery will go dead within a month from parasitic loads. The switch is a lot easier than removing wires from one post of the battery.
2) a wireless thermometer (battery-powered) to keep track of fridge temps. Mine cost $10 at Wal-Mart. Could be considered "food safety".
3) pigtails to allow you to connect to 15/20 amp and 50 amp plugs. The 30 amp plug is the most common and the most abused at campgrounds with electric.
- comfort: a memory foam mattress pad. Makes sleeping on the bunks comfortable instead of painful.
