2nd Air unit on fifth wheel?

[cj41foley]

I'm probably going to be putting a second air unit on my new fifth wheel to help out on these hot humid Alabama days. Anyone done this before? I know it's supposed to just go right where the 14X14 vent is which will have to be either in my hall or bathroom. What do I have to do for power? TIA

do you have a gen or use hook ups ??

[cj41foley]

99.9% of the time we have hook ups

Do you have any extra space in your power center? like an extra space for a breaker? Then you could just add it on that way and wire it to the thermostat... unless you jsut want to operate it on your own....

Hopefully you have a sep breaker on your gen for a second unit, I do because both a/c's won't run on the same leg in my 5er. One at a time, but that defeats the purpose of having 2.

Check with Sunnybrook, it may be pre-wired and just tucked behind the vent assembly. The down side if your trailer is not 50 amp, you will not be able to run both at the same time off 30 amp service. One way around this is to run a separate feed wire from the ac to the compartment where your shore power cord comes out and plug it into the 20 amp outlet at the campground, that way you can run both without having to mess with a power management switch. I know what you mean needing a second unit, we were at the beach in June, the one 15K unit during the heat of the day was struggling.

30 amp and you'll be blowing breakers (hopefully) or worse, blowing your distribution panel. You can get it upgraded or run a second power feed as suggested above. I've been wanting to do this as well, so I've been doing some research, but mine's (thankfully) a 50 amp feed...

o.k., checked with Sunnybrook, they told me that it isn't pre-wired since it's a 30 amp service and that even if it was 50 that 2 airs would have it maxed out and that stuff like my refer., and water heater would probably run off my gasa all the time with 2 ac's going. My 1 15,000 unit had my camper at about 75 degree's inside and it was 100 outside, they told me that was great, my concern was that the unit was running constantly but they told me to run it and don't worry about it, said it wouldn't hurt anything running constantly, they also told me that most ac's do run constantly especially on like pop-ups, so I guess I'll just let it rip on the parks power bill.

If you are 75 degrees in 100 degree weather, unless you have kids opening and closing the door all the time, you do not need a second air. I have a second air on a 40 ft, only stays at 75-79 degrees with near 100 degree ambient temp, but have 3 kids opening and closing the door all day, and my wife likes to stand in the door and talk with the door open. I think you are expecting too much out of it. Run it and forget about it, they last for years and years.

I don't know if your fifth wheel has slides or not but if it does here is something to think about in adding an air unit. My 36ft Prowler has three slides, two of which are in the living room. The window on the passenger side slide located near the rear of the trailer lifts up. I went to Walmart after measuring my window opening and put in an 8,000 cooling air conditioner by admiral, with remote. Fits right in the window and comes with little blocking slides that fill in the gaps on both sides of the air unit. Plug it inside the fifth wheel and combined with my ducted roof unit I am able to get temps in the 70's when the ambient temp is in the low 100's. of course you have to take it out each time that you move but it is a clean set up and does not look hokey. Not that that woulld matter to me but I have to live with someone to whom it would make a difference if it looked a bit red-necky (New word) Oh yeah, I think I paid less than $150 out the door.
