Why couldn't you?That's what you do at a campground

Maybe? Much more specifics needed to answer the questions.

You should be able to power the fridge with 15-20 amp home outlet. I would use a heavy cord.

Most slides will require a well charged battery to function, and likely won't operate on home outlet only.

Sure, but you need either a correctly wired receptacle or the correct adapter.

I'm not sure what on earth prompted this question, but, no, not directly.

If I were you I'd be cracking those owner's manuals.

Contrary to all the nasty responses, yes you can, as long as you get the proper adapter cables. I do it all the time. The household current will keep your battery charged, so the slides will work, and it runs the fridge, just like it runs your house fridge. This is how we keep ours plugged in between trips, and during loading for a trip.

It depends somewhat on what amp rating you have on the receptacle that you are plugging into in your house. I have done this many times but I am careful about overloading the circuit. If I'm only interested in running the fridge and few lights then usually a 20-30 amp breaker outlet works fine for me. If you're worried about overloading a circuit can you use the propane to run the fridge?

My slideout on my fiver only runs off of the battery system. No batteries means no slideouts for me.

Can you use house current to power the slideout? Thanks for the help folks.

Yes to 1, provided you have a properly-wired 50 amp receptacle to plug in to. This means a separate breaker in your home's panel, wired to the plug. I have a 30 amp system at my house for my FW. This will run everything in your FW, including the a/c(s).

Yes to 2, using a 50/20 adapter. It will run everything but the a/c. Since slides run on 12v, whether electric or hydraulic, your batteries need to be well-charged.

WE have a 50A 5vr
For over a month we lived in it along side house waiting for escrow to close (house was empty)

We were plugged into a 20A outlet in garage using 2 adapters....50A to 30A and then 30A to 20A/15A

We ran the fridge and TV on electric......also the converter which charged batteries.
WE used 12V DC system to operate the lights, the water heater on propane and slides

On a typical RV the frig can operate on either 120 volt (household power) or 12 volt (battery) with propane. The slide motors use 12 volt. When hooked up to household power, a converter, converts the 120 volt power to 12 volts to run the lights, other 12 volt loads and charge the battery.

So, the answer to both questions is yes, you can use house current to run them... The frig will only need approx. 500 watts - so any household receptacle should supply that - you will need adapters to get from the 50 amp cord to a receptacle plug. If you have a good battery the slide will operate with or without house current. The converter will replenish the battery within a few minutes using 2 - 500 watts to recharge the battery. If there is no battery the converter may not supply enough current at 12 volts to operate the slide motor.

Just don't try to run the AC while connected to a typical 15 amp receptacle... And use the shortest extension cord possible - 10 or 12 gauge.
