Question 321RSTS 15amp to 50amp question

A question for those who have a 321RSTS.. or really any of the Eagle 5th wheels.

When parked at the house I was thinking of getting a 15amp to 50amp adapter and plugging it into the RV in hopes of charging the battery and possibly running the residential fridge in the unit to prepare it for a trip. Has anybody tried this, would just running the fridge and charging batteries pull too many amps for the cord.. last thing I want is to burn down the house.. or worst damage the RV.

It will charge the battery just fine, I did mine the other day and the power monitor was reading 8-9A with the battery charging and bathroom fan going.

Not sure about running the fridge, the initial spike of power consumption might put you over the edge and trip a switch? Only way to know is to try...

It will work fine as long as the mw and ac are not used. We do it all the time.

I run the fridge all the time using an adapter. No issues at all after years of doing this.

As other folks report, yes it works fine. I found that a 15Amp circuit would not support the A/C but a 20Amp would. With our first TT I could back it into the drive which was close enough to our kitchen to reach the 20A plug there.

Like RedHorse said - you CAN run an AC on a 20 amp circuit - but watch the extention cord size. I used to have to park my rig on the street several hundred feet from the house. I would run the "orange" 15 amp extention cord that I keep in my garage out to where it could meet the larger 30 amp cord coming from the rig - then use an adapter.

It charged the batteries, ran a few lights and got the gas electric refrig cold without using gas.
One particularly hot day while loading the rig for a trip, my wife reached up and turned on the AC without thinking. It ran fine for about 5 minutes then quit. The extension cord was starting to melt and the blower motor fried on the AC. I'm surprised it didn't kill the compressor but it didn't. I ordered and changed the fan motor myself and it was still working 5 years later when I sold it. But that was the toughest repair I ever did. I should have taken the unit off the roof but I didn't - I managed to change the motor from the top while sitting on a HOT roof. Had to bend the condenser a bit just to get it in and out from that end.

Bottom line - If you're going to do that - warn the entire family OR turn off the AC circuit breaker AND warn the family.
