We've been stationary for a few months. We don't have full 50 amp power hooked up here yet so I haven't been running the A/C. Today got too hot so I disconnected shore power and turned on the generator to run the A/C for awhile. We were doing some family stuff and when we came back, there was a big puddle of water on the floor and the A/C was dripping.
My father-in-law stayed in the trailer about 7 or 8 months ago and it did the same thing to him. I chalked it up to condensation at the time.
Any ideas?

Time to head up on the roof, there is usually a drain hole (weep hole ) that often can get blocked up with debris.

Hi Cameron, sounds like your air conditioner drain tube has fallen off, it should drain onto the roof, if you take the air conditioner cover off, look for a drain tube, it could have cracked or fell off, they do build up a lot of condensation, that's where I would start, let me know what you can see and we can go from there.

Thanks. I'll get up there after work tomorrow.

Well, its not the drain. It barely had any water in it and it started dripping heavily again. I'm going to keep trying to figure out where the source is.

Check the coils of the AC for dirt / blockage, which may be causing the AC coils to freeze up at times. Also, some AC units will freeze up and drip inside if they're run on a low fan speed or too many air outlets are closed.
You need good air flow across the coils to stop them from icing.

Check the AC/roof gasket. This shrinks overtime and as the condensation drains onto the roof it will accumulate into a puddle then seep in between gasket and roof and pour into your rig. The gaskets are pretty cheap and not too difficult to change if you have someone help you. Basically you have to unbolt the AC from inside then have someone lift the AC off the gasket.
Important to not tighten the new gasket down too much there are hash marks on the gasket to guide you.
Just a thought, hope it helps.

also remove inside cover and check the inside drip pan for blockage at the begining of the tube.......you said it is dry as a bone outside on the roof ....that would tell me the inside drip pan has clogged from mold growth in the tray and tube and now just fills and spills over.....
simple fix would be to take off rooftop cover and take one strand of wire out of a piece of romex about 4' long insert it in a spinning motion up the drain tube into the inner drain pan.........you might want to run the A/C an hour or so so you have water built up in the inner pan , this will answer the question fast if you clear the tube..
if your running the A/C and dont have a steady stream of water dripping off your roof its either clogged.....not working....or as others have said the gasket has gone bad between the A/C and the roof
good luck wish I was closer to help

Check the hold-down bolts that hold the A/C unit to the roof. We had a problem with water coming inside the coach too and when I checked the bolts they weren't even hand tight! Guess they vibrated loose on the bumpy roads. Anyway, I tightened them down and no more problem. Take off the inside grille and you'll see the 4 bolts I'm talking about. Don't over-tighten them because you'll squish the gasket too much. Bet that will cure the problem and it's a really easy fix!

Well, as I started poking around, I found the holes. Two screw holes that had no screws in them. Previous owners just tried to put tape over the leaking area (didn't even get the tape on the holes). I moved the sheet metal back into place and put screws in. However, our trip to Kansas proved to be relatively cool so I didn't run the A/C. We're back in California now and its supposed to be a scorcher this week. I should know soon whether my fix worked or not.
