Friends of my mom were planning to do RV life for a year or two (while wait-listed for a retirement community) but they decided to rent one for long vacation to be sure. The husband bought the powerbank while it was having a sale, sure they were going to buy an RV as soon as they got back. By the time their vacation was over they vowed to never set foot in an RV again, and he sold the powerbank and AC to me for $400 less than he paid for it. He also hadn't accounted for the Delta Pro being 100lbs, and they had trouble getting it up and down steps.
