I added carpet to the camper interior and installed an exhaust fan to the reefer unit. I still need to hook a thermostat to the exhaust fan. We really won’t need it in November when we go to Virginia, but it will be great in keeping the reefer cool when camping here in Florida. I made a newspaper template for installing the carpet. I paid 15.00 for a 5 foot by 9 foot remnant at a carpet store. I could have scrounged for some used carpet but didn’t want to mess with spraying it and cleaning it for “cooties”. I still have some other upgrades and modifications to make, but I don’t know if I’ll get them done before we leave for VA. I plan to install two 6 volt golf cart batteries and install trailer brakes.
