Adding 2nd A/C, more questions.

I added a second A/C to my 33' 5er. I wasn't going to go through the roof with mine though. I bought a combo AC, Dehumidifier, Heater for mine. It stands in it's own little spot by the bedroom sink. I vented it to the outside via a 3 louvered dryer vent style fitting so it keeps the outside looking neat and sleek. The A/C will freeze you. The dehumidifier pulls moister out of the air and sprays it out the vent like a champ. I couldn't believe there was that much moisture in the camper. When we travel, the bedroom slide pushes the bed right up against the A/C to keep it nice and secure during the trip. It most likely cost a fraction of what an A/C on the roof install would cost.

It used to take about 2-3 hours to cool down after setting up in the summer. Now, it takes about 30 minutes to get comfortable.
