1978 Dodge Sportsman "Travette" RV Cherry 4-3-13  
My boyfriend just purchased this motorhome, but we're clueless. The guy who sold it to us briefly explained certain things, but was vague overall. So what I would like to know is...

How does this Rv's electricity work?

When we went to pickup the RV, he went over the propane tank, said it was empty but that it would work for the fridge, hot water, and stove. Briefly turned on the fridge, and noticed it did start cooling pretty quick. He was parked in front of his driveway, so he had an extension coming from his house to connect the RV, and the lights worked... But then as soon as we took a test drive, all was completely pitch dark, and even the fridge wasn't running anymore.

Which brings me to my question, is propane supposed to run the electrical stuff as well... or am I missing something here? He did leave us a couple big plugs to be able to use, but didn't explain where they go.

Treasure hunt time.

Somewhere there is the battery to run the interior lights on 12 volt.

It is missing, very very dead, or has an electrical problem causing this.

Sometimes both batteries are under the hood.

Sometimes the House battery is mounted to the van frame under the RV body. Crawling around on the ground is required to find it, 75% of frame mounted batteries are just behind the cab doors on one side or the other.

Next you have a unit that might have dual 110 v / 12 volt lighting or it may 12 volt only.

Its right on the edge of the change over time.

If it is 12 volt only there is a small charger and power supply called a "Converter" mounted in the cabinetry and mostly mounted on the floor, but not always it could be inside a overhead cabinet also. Usually a vented metal box with 12 v and 110 volt wiring run into it.

This will provide 12 volt power when you are plugged into 110 v power. If it is working right.

110 v Power cord is usually behind a little door or flap on the outside. Plug it in and see what works. It sounds like the seller gave you the adaptors.

I am a little worried about the LPG tank being completly empty. Please becarefull about leaks and such on an old unit like this.

Good Luck
From there good luck.

Back in the day a relative of mine had a 20ft Travette(had years of awesome family vacations in that green/white RV).........relative bought it new in Bakersfied where they were built. Frig depending whether it's Swiss made or Coleman unit requires 12 volts to the unit so the electrical relay will allow it to run on Propane when 110 is not available.........basically.....a pilot light takes care of expanding-contracting the ammonia's what makes the fridge "cold". Battery and 120 volt to 12 inverter should be under the sink area. 110 connector on his was located in the fridge exterior access panel on driver side............hope that helps.......and too ensure trouble free transmission..........Chrysler installed drained plugs on the all one needs to do(with battery disconnected)rotate engine until torque converter drain plug is visible......make sure to drain transmission pan too.
