The two standard 13.5s are not enough to cool the unit adequately in the south's extreme heat/humidity combination. Last year in Houston with exterior temp about 96-98, best we could do was 87 inside with both units running since the night. They were not frozen or anything like that. The fridge then had problems keeping up and could only get to the 45-47 degree mark. We added a 15 and had much better performance on our Florida trip this year. FR hasn't admitted to themselves yet that it's not really adequate for summer use in the south. Hopefully on future models, they'll have the 3rd AC unit either standard or as an option.

Don't know for sure on your unit, but my Flagstaff has 2 ducts running the length of the trailer and I tapped into the duct and put an outlet in the bathroom. You might look at yours and see if that is possible in the bedroom.

Joker, did you add a third a/c unit to your coach? I went looking through old threads and couldn't find who did that. That was apparently quite effective.

On a previous motorhome, I replaced a 13.5 with a 15 for about $600. It was a great improvement, maybe because it was bigger or maybe because it was new.

Sounds like normal 13.5k BTU A/C operation to me. my A/C always works great in extremely hot weather. that is untill I`m parked where there is no shade! When I have a site with shade my 32ft. trailer will cool down to 70 deg. with out issue and will actually cycle! just over the 4th we were in a campground with no shade and temps that averaged 100deg. the A/C could barley keep 85 deg. I just deal with it.

I posted about adding a 3rd AC unit in the Speaker thread (Speaker Replacement, which contained a few other off-topic things as well). We put it where the ceiling vent was in the kitchen area to keep the install simple and more cost-effective, after making sure the generator and thermostat could handle a 3rd unit. When we camp in the desert, where there's direct sun and no shade, the best we could do with the stock units was 10* below outdoor temperature. (You can feel the heat coming in through the walls from the sun.) With the 3rd unit, we get another 10-20* of cooling. Expensive, but if you want it to be 72* inside when it's 95 outside, it's money well spent.

Yes, we replaced the vent port near the kitchen with a 15k btu unit, but I did not make a posting about it before. We are going to have a new vent port cut. There's some requirement for venting if using combustible fuel cooking indoors plus we like the fan to pull in fresh air when we are out in fair weather. In the heat this summer, the combo of the three units performed very well on our Orlando trip.

DUCK TAPE!!!! That is what we did!!
Don't you know it will fix about anything

We taped the back of the vent and placed it back up!

For Joker and Motowood, did you look into the effectiveness of replacing the existing 13.5ks with 2 15ks? I'd guess, from previous experience, that would be easy and about a $1400 job. What made you decide on three?

I decided on three because going from 27k btu to 30k btu is only 11% capacity increase, but going from 27k to 42k btu is 56% increase. Plus, I now have more redundancy. If one goes out, I still have 2 functional units. I suppose another 13.5 would have been almost as good, but I figured I wouldn't regret getting the bigger one to start. There is apparently a potential problem with freezing the unit(s) if I'm using the ducts exclusively, but if I'm using both units, then it's really hot and I'm just 'dumping' the outflow, so it's not a real concern for me.

You know I thought the same way until I landed at a campground with under size wires and low power. The folks with 13.5's ran on days my 15k would not turn over.
