Found out leaving the tow vehicle plugged in the the camper will drain the tow vehicle battery pretty quick cause of the 12 volt fridge running all the time.

The Lance camper I owned had a relay that shut off the tow vehicle power if it dropped to less than 10.5 or 11 volts. So now I gotta put one of those on the Riverside. Ya would have thought Riverside would have done that!

Has anyone been successful in getting a wiring diagram for their camper from Riverside?

Hi Richard,
You must have a newer Retro with a 12 volt-powered fridge.  All the others run on either 115 vac or propane.  They need 12 vdc to control things, light the propane, and light the little LED's, but they draw negligable 12 v. power.  Don't know why Retro would put a 12 vdc-only fridge in a small trailer, since they do have a propane tank. When I set up camp I always unplug from the tow vehicle, so I don't need a shut-off relay.  Does the fridge in your TT have a freezing compartment?  I wonder if it's a thermoionic one like the 12 volt-powered coolers I see in stores.  I have a 36 quart Igloo cooler which draws about 5 amps DC constantly.  That's too much for boondocking, even with a larger capacity battery, Even a 100 watt solar system in Arizona wouldn't really keep up with a constant 5 amp draw.

Another note:  Mike on this forum says some new Retros have the Everchill WD-282FWDC which is 12 vdc only and actually has a compressor.  I found a post online claiming it draws 8-10 amps on startup, then drops to 3 amps.  3 amps would be 72 amp-hours per day.

12 V only reefers are a bad idea. But, leaving a camper plugged into the TV only makes it worse. An absorption reefer will run a couple of weeks on a 20 lb propane tank.

Thinking I may change it out to a three way frige.

3 way unit are not  as reliable as 2 way propane/120v. The 12volt option draws  a lot of amperage and has been know to have problems. They are not as popular as they use to be. 2 dealers in Reno talked me out of changing mine over. Like Mikes said you can run on propane for a good while. Just have to make sure tt is level. GBA!!SVJ

some people go to inverter and solar to run the fridge on 120v not sure how this works. The 12vdc  I looked at pulled over 2.2 amps at 13volts. May have been larger size than you have good luck GBA!!SVJ

Tri-power refers are a bad idea. My father-in-law was always replacing them in his motor home. He must have put at least five in that I know of. In my opinion dual power(120/LP) is probably the best option.
