2nd A/C ?'s on Jay Flight or White Hawk

If I order a Jay Flight or White Hawk with the second a/c option, would the second a/c be controlled by a thermostat or are these the blast from the ceiling units with the control knobs on the unit?

If I get the 50 amp svc. & a second a/c can I still use 30 amp camping sites as long as I don't plan on using the second a/c?

All of the dual A/C Units I have seen have a Thermostat that says Station 1 and Station 2 or Area 1 and Area 2 so the A/C's can be set independently.

If you use the adapter and hook up to the 30 amp connection then you have to do everything as if you were a 30 amp coach. There are good amp guides on line as to how many each appliance pulls.

Our 2015 JayFlight had 2 ACs and only the main AC had a thermostat and was ducted. The other was just a simple roof mount.

Yes, you can use a 50 amp RV at a 30 AMP site with care. If you search the forum for that you'll find a lot of great threads on the topic of what you can expect to run and not.

Just be aware a 30 amp service provides 1/3 the electrical power that a 50 amp service does. You may have to limit your heating appliances, toaster, MW, hair dryer etc if you have an AC running and are on 30 amp service, with 50 amp you most likely won't have an issue.

Good Luck. and Happy Camping

The models I am considering are the 27BHS (JF) & the 29BH (WH). Are two a/c's overkill? We do use the camper quite a bit in the heat of the summer when it can be 90+ on some days.

If you can get two ACs then get 2 ACs. It's way cheaper and easier to do it up front.

Peak summer, full sun and higher humidity... You'll want 2 ACs.

Our Flight has the second AC in the master. It has it's own thermostat as part of the unit.

I have 2 A/C's in my 28BHBE, I bought the one off the lot that already had it installed. MOST of the time the main A/C is adequate. When the outside temp gets above 90º I like to run the one in the MBR also. My second A/C is independent and has it's own thermostat etc. and just blows air from the unit itself. The main A/C is ducted to the MBR also though so the 2nd unit really isn't needed unless you like it COLD. IMO, it's definitely worth it in the south during the summer.

As others have mentioned, we run our TT on 30amp service when needed. You just need to be cautious of what your running when. It is worth noting, you CANNOT run both A/Cs simultaneously on 30amp service for long, if at all, before something trips. HTH!

Don't know if all Jay flights are the same but my Jay flight 28BHBE has the dual ac's. the main one has a wall mounted thermostat but the bedroom one has the controls on the ceiling unit itself. It's not an expensive option so I'd rather have it and not need it then add it later...

Definitely not overkill, I don't see anything over 90F and still wish I purchased that option.

On our 16 Eagle we have two t- stats. One in the hall by the steps. And one in the master for 2nd unit. We had to close the vent on the ac which blows towards the thermostat.To keep it from cycling on and off.Just found out on the forum if you close both vents on ac. It forces air through the ceiling duck-work.Not sure about your camper.Happy Trails

Our 2012 has two A/C units, both tied to common ducting and both have totally separate digital thermostats. With this configuration, we can run one or both, plus setup two zones.

Both units have vents as well we can cutoff to force are into the ducts, this allowing us to run the unit opposite the space in use and reduce background noise while we occupy either half of the RV. Well designed!

We have a 2017 27BHS with 2 AC. The one in the bedroom does not have a thermostat it is just a blow from the ceiling. There is a vent in the bedroom from the main AC. So it will cool from the main AC. We figured it was a cheap option and would rather have it than wish we did. There is not a vent in the back bunks so picking up a couple clamp on fans is on our list of things to get along with a ladder to get in the top bunk.

30 amps X 120 volts equals 3600 watts of available power

50 amps X 120 volts equals 6000 watts of available power

30 amp service equals 60% the power of 50 amp service. Apparently you meant to say 2/3 instead of 1/3.

You would be correct if 50 amp service was a single 50 amp line at 120 volts. BUT a 50 amp RV service is TWO 50 amp 120 volt lines..hence I said what you have available, 12,000 watts at 120 volts. Or about 3 times (actually more ) of the power available on a 30 amp service.

Waggs, THANKS for straightening me out. You are 100% correct. I completely forgot the 50 amp rv service contained two 120 v legs. I feel kinda stupid now but I'll get over it. ����
