The 21FBRS is a tough little camper. I picked mine up in Iowa before Xmas and took it directly to Plant Vogtle Nuclear Powerhouse in eastern Georgia. I worked there for about three months with 15-20 degree weather, storms, rain and a tornado or two. It was warm and dry...not one leak. I heated it with a little electric oil radiator. Plenty of hot water and the heated mattress is to kill for! Since then I've been to Lake Okeechobee for a month of fishing....hope you enjoy yours.
