1The air coditioner does run on Electric. 110V 2. No you do not have to unhook the battery 3. Yes you need to put water in the hot water heater so you do not burn the unit up.

Hi, hopefully it is just your drain stopped up. If you can climb up on the top of the trailer, on your air cond. unit will be a drain. It will be about 1" around and will be located close to the bottom of the unit. It may have a hose connected to it or it may just drain on the roof. When you find this, see if it is plugged up with dirt, etc. You can stick something up in it to unclog it, but be aware not to jab the coil tubing with what ever you are using. You may be able to use a shop vac or compressed air also.
If it is not stopped up, depending on the age of the unit, the condensate pan, (which hold the water) may be rusted through. You will have to take the top of the unit off and a couple of covers to get to the front coil (looks like a radiator). The pan is underneath the coil.
Hope this helps and I hope it is the easier of the two. Mark
