I bought my brothers pup and decided to make it mine. Ithe was in pretty good condition, but I wanted to make it a little more comfortable for family camping in area without hookups. I started by gutting out the old 15amp converter with the wire you would feed into the side of the camper. I retrofitted the beefy shore power wire with a twist lock connector and plug in with door to protect it from the elements. I then got to work installing a solar power generator I the storage compartment that the old converter was housed in. For the solar setup I opted for a Midnite Solar Classic 150, an AIMS 1200 watt pure sine wave converter with change over switch and a battery bank of six golf cart 6 volt batteries run series parallel for 690 amp hours of storage. It's all supplied by 1200 watt solar array that are grouped in 300 watt strings running 60 volts each. The side of the bench that houses everything has a shore power only GFCI outlet, 2 five inch inlet fans on one end and 2 exaust fans on the other controlled by a programable thermostat, 3 12v outlets, 2 USB plugs, SAE port for beefy needs, display for the charge controller, and a bunch of other controls. I wired in a 12v pump and extra outlets thru out that can run on shore power or inverter. I installed and Atwood gas/electric water heater and set the sink up with standard faucet for hot and cold. I can run propane or electric whIle plugged in, can also power the water heater with the inverter with dedicated shore/inverter switch to use up extra electricity during the day. To vent the batteries I set up two low inlet vents and two forced air exaust ports that are timer controlled. I also set up two deep cycle chargers that will charge up the batteries when plugged into shore power. I replaced all of the water connections and put power outlets of various types outside.
