Do I need two AC units on a 30' or 31' trailer?

[99Limited34]

We have one 15K unit in our 34 footer and it's more than adequate, we've had many 90-95 degree days and have never seen the need for a a 2nd AC.

coach with 30 amp service will require modification to carry 2 a/cs also only 1 roof hole is prewired and has DRAIN TUBE so a proper installation would be very expensive, i say live with it or or sell the farm and build the trailer the way you want it.

If you check the original post, LJD is asking for opinions on ordering a new Airstream from the factory. Seeking options on a clean slate.

I agree with the points you made about existing coaches. That's why I don't have a second AC—yet.

We upgraded from 13,500 to 15,000 btu unit on 30ft Classic last year. We live in Biloxi, MS and have traveled for 2 summers in the South. The upgrade made a big difference. We are comfortable with the one 15,000 btu unit.

We ordered new from the factory. Since all our family lives in the south, and we were soon moving to TX, we knew we wanted two A/C's. We also got the full awning package and deleted both the skylights. I don't know how that would affect the resale value but we weren't concerned about that.

I will say it's been worth every penny. We have had shaded spots but lost a great site last time we had to move. We are in full sun right now and we do just fine. In the peak heat of the day the 15k unit will run constantly but not always on the high fan. The bedroom AC will cycle off but we have our windows covered in that reflective bubble stuff because of a street light right outside our bedroom.

When your spending that much on a new unit, it's a minimal cost to add a second AC. Even though you will need 50A service for both, you can still hook up to 30A and run only one.

From a resale point of view, since we live in the south and we have experience camping in hot weather, I would only buy an RV that large with two units.

When we retire, we can chase 70 degree weather, right now we don't have that privilege.

I won't hurt. If it is really hot I have been know to sleep on the couch.

1 should be fine. Our 34 ft. Limited has 2, a 15k btu and a 13.5k btu.
Used the trailer last week in Texas. It was 105.. Only used 1 AC

I wouldn't do without two. Having lived for the entire summer in Texas, north and south, with a better insulated brand of aluminum, aerodynamic trailer but with one 15k A/C unit, there were weeks that keeping the trailer below 80F wasn't possible. It got old, to say the least.

With 50A service one has options should one want them. No question that it becomes a more valuable TT with twin A/C units.

I have 2 AC units and glad to have them!

We camped last June at Perdido Key and struggled to keep the interior cool. The only way to keep the temps below 85 degrees was to close the rear bath. July in Biloxi had the same issue. Granted we were in high humidity, direct sunlight but my only other option was to stay home...

The times we were able to get shade or when the humidity wasn't so high we were fine, the compressor would cycle as expected.

We might be the exception to the rule but we do camp all during all 12 months, summer usually consists of trips to the coast and we will take a full sun location if it's the only option...your milage may vary.

An update...we switched to a 34' and added a 2nd AC unit

We would NOT be camping in the heat of summer, down here, without the 2nd AC

I completely agree. Even with two, sometimes we've noticed that it is still a struggle to get the front area of the coach near the sofa as comfortable as we would prefer - and that's also without any skylights. I do not think we would be using ours near as much as we do during the summer without the rear bedroom unit.

This thread is 7 months old - hopefully the original person has ordered and received their trailer by now.

We just have one A/C in our '95 30-foot. I can see where a second one might be necessary in the worst heats, though. Fortunately we don't camp in that often enough to make it an issue for us.
