Towing truck camper (expecting first experience today)

Batteries fail w/o warning, load test it, observe headlights while starting, buy a battery, rent a car, etc options, may/may not resolve. See if you can pay the tow truck for alternate delivery. You may have to remove the camper but I would not leave it at Walmart. May have to find alternate sleeping arrangements. Maybe a mobile mechanic.

Just saying be prepared, but hopefully resolved easily,
