To run the AC I use a HD extension cord and plug into the washing maching receptical in the garage, which is a dedicated circuit.
I strongly reccommend you not to get anywhere near the 220VAC Clothes Dryer Circuit in the wash room. The clothes dryer connector looks very similar to the shore power cable but they are two different type circuits... You will fry everything in the trailer if you dont know what you are doing. Even asking an licensed electrician on what do is harmful to your trailer as most house wiring electricians dont know the RV wiring schemes to make good decisions.
Using the dedicated WASHING MACHINCE 120VAC 15A Receptacle is perfectly ok to use but just wanted you to know the 220VAC CLOTHES DRYER connector is NOT OK to use unless you know exactly how to modify an adapter to use it.
Didnt mean to jump on PU Campin by any means - Just me thinking out loud for you to be very cautious in the wash room area. A replacemnt RV fridge runs around $1400.00. Just because the Dryer uses a three prong connector doesnt mean you can use that with you RV Shore Power three prong connector.
I appreciate the warning, and it is an important caution to those it applies to. However, all my appliances are natural gas, the dryer runs off NG and 120V. In fact, I do not have a 240v receptical anywhere in my house
The reason I like to use the washer receptical is code requires the 120v receptical for the washer to be on a dedicated circuit, even in 1981 when my home was built, so I know I have a full 20A available.
And yes, the older 3 prong 240v cloths dryer receptical NEMA 10-30, and the 120V NEMA TT-30 look a lot alike, which is part of the reason the NEMA 10-30 is no longer allowed by code, but this did not happen until NEC 1996, so a lot of installations exist. If someone is unsure, a quick check with your frind the Digital Volt Meter will put this question to rest. A NEMA 10-30 you will get 240 hot to hot, and 120 from either hot to ground, where a NEMA TT-30 will give 120 hot to ground and hot to neutral, and 0 neutral to ground. However, I can gaurentee you will not have a NEMA TT-30 in your washroom, these are almost exclusivly used for RVs and thus rarely used elsewhere. If it is 3 prong, it is most certainly a 240v NEMA 10-30 and should not be used.

PUCamping - I was directing this to SKYPIGG for his info... Should have had his name up front on it... I knew you was already aware of all of this... Sorry about that...
It is amazing some guys will take a look at the old DRYER three prong receptacle and think they can make up an adapter and plug right into it... you know "How hard can it be - its only three prongs" I know of one making that mistake last season... Blew up a bunch of things in his trailer. And the sad part was he read all these comments about what might happen and did it anyway... "I'm smarter than the average Bear" I guess haha... These are the same guys that will put a deadman plug on both ends of a cable hehe...

I plug mine in all the time, just can't use the A/C. I used to use the A/C regular until one day I put a volt meter on the line and found out I was getting 96 volts with the air running. Man was I lucky I didn't damage the A/C. The circuit box is on the other end of the house and it's just too long a run.

Great questions and comments here. The poster whom mentioned the round plugs and getting hot. TOTALLY AGREE!!
I want to heed some warnings to those out there. Please becarefull of pulling too much current on that circuit and tripping the breaker too many times.
When I met Amy she was renting her RV space on the side of the garage out for a few months. I happened to walk by the outside recepticle and noticed it was scorched black and the round adapter was slightly melted. Just by looking I knew it was running a 30amp setup in that 15amp plug. I unplugged his RV and found the prongs on the plug were melted almost all the way through.
I promptly permitted with the city to self install a 30amp RV Outlet just above the 15 amp recepticle.
The 30amp box and associated wiring with breaker was all purchased from Home depot.
30amp RV outlet box with flip down cover
50' of three conductor 10 ga wiring
30 amp breaker for fuse box
Wire Tacking Nails.
Total cost was about $180.00 if I remember correctly.
Lucky for me we have access to the attic space above the garage so the wire pull was very simple. I only had to follow where the 15amp line was and space them as required. It took about half the day by my self to do the install but it was well worth it. An electrician could probably knock it out quicker.
I ended up replacing the 15 amp breaker, wiring and recepticle as a safety precaution at the same time so basically it was close to doing twice the work.
I like the idea of pugging into the dedicated 120v dryer circuit. That is a very good point.
But if you have the ability and access to install the correct RV outlet by all means check with your local code enforcement to see if you as a home owner are allowed to install your self. Each state and city is different. We are required to get a permit and inspection but can install our self.

That's awesome...I'd like to do the same thing but there is no way I'd do it myself. About how much would a pro charge to set up a 30Amp outlet? I just completed putting in a concrete driveway/slab into my backyard for my TT and would like to have the option of plugging it in.

I have my son's 50 amp fifth wheel plugged in to a 20 amp outside outlet right now. I have tested all the appliances, including the AC and the washer dryer, with no problems
I usually have my Tioga (30 amp) plugged in all the time. I have even used a small electric heater in there when company is here. No problems.
The problem is not if any appliance will work, it is how many will work at the same time.
The A/C will work, so will the Microwave, and so will the hair dryer. But you can't run all 3 at once!
If you can, you better call an electrician to check out your breaker panel. It is allowing way too much current to be drawn over the wiring designed to carry 20 amps.
