2nd AC Unit

Folks,

I have a 2018 305RL. It has the single AC unit on the back, and I am looking to put a unit on the front over the master bed. Any recommendations, units to avoid, issues installing, what to avoid? Any info appreciated.

Thanks,

Matt

Just be sure to get a low profile unit. Mine is and I am still at 13'4" in height. Wouldn't want to be any taller. Not sure if the low profile is the reason, but the unit is only 13,500 BTU (or whatever that number is measuring!).

Should not be a problem as my 2014 305RL came with 2 factory-installed AC units.

I purchased 2 from Panther RV Products for my DP on Black Friday. They had the best price I could find on the Penguin 2 low profile ac/ heat pump 15000 btu models. Hardest part of the install is getting them on the roof and the old ones off the roof. I installed them at work and used the forklift for that part of the job.

We had a front AC installed on our 2018 305RL. Same brand as the rear, I believe it’s a Dometic, 13,500 BTU rear is 15,000 BTU. I would go with a low profile unit. It’s not going to be as quiet as your rear unit.

I've heard some good things about the Colman units, one thing was the soft start

I installed this one:
Dometic 640315C Penguin II 410 Amp Low Profile Rooftop Air Conditioner(Polar White)

Along with this ceiling panel since our 343RL did not have ducting or thermostat control wires pre existing

Dometic Air Conditioners 3314851.000 Adb Man Control PLR Wht F/All

These parts were purchased via Amazon in late 2016 but at heluva lot less dollars *$625) then today (~$1025). Easy install using the 120VAC prewired bedroom vent. I assume that you have a wiring box next to that vent. I used a 20 amp (not a standard 15 amp), 120VACwall plug as a connect device for the existing to the new a/c wiring. This added another plug to the bedroom that is used primarily when we vacuum

Using this 13.5 a/c, we have found will often cool as well in warn, not blazing hot days as the original 15K ducted unit since the cool air 'falls' down from the bedroom and for sure with both running, way better. As far as cooling just the bedroom - it can get about cool enough to become a meat locker

Thanks for all the input. Yes, the site is all set up for the second AC.

I expected that it would be noisier, like the AC unit in some motel rooms. Not much you can do. And the only time we would use it would be those blazing summer nights for sleeping.

Thanks again.
