Then a roof AC with a 3rd "fan speed" choice..like as in LOW speed/quiet mode.... for sleeping. Most roof ACs I have heard, [and like the one in our former Casita] sound like a 737 in take-off power. Cool they do, but these reasonably-well insulated fiberglass TTs are easy to cool!
Hollybee: With all due respect those that think the overhead A/C units are not loud may have some diminished hearing. Maybe the placement in a 21 with bed up front helps a little bit too but they are still undeniably loud when seated at the dinette. One of the biggest complaints I see in small fiberglass trailers is the A/C noise. The standard Dometic and Coleman units are oversized and comprised of antiquated technology.
It goes way beyond just another speed on the fan. I have posted this in my custom A/C thread:
“Imagine for a moment if a trailer manufacturer like Escape took the time to engineer and implement a sleek, split system that
-provides cooling, dehumidifying, heating and fan modes
-is whisper quiet inside and outside
-has inverter compressor technology that reduces amp draw and improves dehumidification versus an oversized constant speed compressor
-provides cooling to 115F, heating down to 15F
-lowers overall trailer height
-creates less aerodynamic drag
-provides for a nicer overall exterior look/profile (especially on smaller trailers)
-has less weight (and possibly the ability to position condenser underneath or where the weight might be desired to positively affect tongue weight)
-provides more room on roof for solar
-no roof opening or opening used for passive ventilation/light or add'l fan
-creates more headroom inside trailer
-auto restart and compressor protection time delay (set EMS on 15 sec delay instead of 2:16 just to protect your A/C)
-no condensate dripping down side of trailer
-easily run on 2KW generator (with no hard start capacitors or SmartStart system to worry about)
-with economy mode (580W) possible to run off inverter tied to lithium battery bank and solar?
Those that want/need A/C deserve better! What's not to love?”
I am realizing ALL of these benefits except the last one with my 9,000 BTUH Fujitsu heat pump. Running off of lithium batteries and solar is still prohibitively expensive but costs are coming down.
