One AC works for 32.6 feet RV(30amp)?

Entegra odyssey/Jayco redhawk 29V, 29K, 30Z, 31F

30 amp class C: 32.6 feet long, has one AC.
Usually RV of that length has two ACs, even for 30 amp.

Does one AC work during hot summer?

We had a 32 ft 2001 DESIGNER with 1 15,000 and it did fine for the 7 years we had it.

My 328 has one 15,000 unit and it'll run you out. Takes longer to cool, but it'll do it.

The answer depends on several factors. 1st: How cold do you need to be? 2nd: How warm will it be where you are camping? 3rd: Are you ok with making a few internal changes when needed?

My experiences, I am ok with being in the mid 70's up to 78 if that is all the A/C can provide. I usually can get the inside ~25 degrees cooler than the outside temp and ~30 when I make a few changes. Although it has happened, I try not to camp when the temperatures are forecasted to be above 100 for multiple days, as not only is it hard to stay cool inside, being outside isn't all that enjoyable either for me and mine.

Sometimes it does happen that the outside temp is above 100 where I am camping and what I do in that case is close the curtains and a/c vents for the bed above the cab and open the A/C drop vents, (mine is an overhead bed, not an entertainment system but I suspect either could be closed off if you aren't watching tv) as doing that helps a lot. If the RV is still not cool enough I drop a nice looking (mountain scene) blanket from the overhead bed to behind the front cab's captain chairs shutting off the front of the RV which helps a whole lot (even with an external cover around the windows and windshield). I also like the additional privacy that provides. Doing those things will allow me to stay cool inside even if the temp outside is 100~105. Here in Texas I found myself once in over 108~110 degrees and I did all the above as well as pulled the slide in (actually just left it in) as on mine, there is only one large slide and there isn't anything I can't get to with the slide pulled in and with all of the above, I have never had a problem cooling the interior of mine into the 70's with doing all of the above even with outside temps ~105+. I had thought about a 2nd A/C although I no longer plan to consider that as I rarely RV (or camp) when the temps are over 100 and can keep the entire unit cool otherwise without any of the above changes needed.

Also, as I think about it, I have some reflectix sheets already cut out that are white on one side and silver on the other, I often keep the sheets in the rear bedroom windows white facing out (looks better imo) and I rarely take a daytime nap but I don't care for much sunlight coming in too early in the morning anyway as I like to sleep in to around 7~8am on non-travel days. ~CA

thanks all. Now I have more confidence on one AC. The AC is in the middle of RV above kitchen, have 4 ducts(vents) in the living room, but has only one AC vent in bedroom. The bedroom is quite far away from living room(other AC vents). should the bedroom have more AC vents to cool down bedroom?

In my Greyhawk 29MV I had problems going below 77 degrees inside while camping in 98 degree weather. We were in full sun; no shady sites on the entire campground. We also did some of the steps mentioned above, specifically closing off the front cab and using Reflectix. If Greyhawks weren’t so porky I would get the 2nd AC. However for my family of 4, weight and OCCC are the driving factors.

This is one of the big reasons I am moving to a Class ‘A’. Ample OCCC, 50 amps, and the second AC.

Class C is easier to drive, and has more robust cab (made by auto manufacturer) and safety features like air bags.

31UL is nice. By the way, any class C has 2 ACs?

The OP was asking about AC. In a round about way I stated I believe the 2nd AC would be highly desired. And I could have ordered a C with the additional AC, however I would have had to sacrifice other areas that were important to me. If I could have ordered a 29MV with 2 ACs that rang up w/ around 2000 pounds of OCCC, I would have ordered one.

I've had my Odyssey 32.6 footer for going on 3 years now and we've been comfortable with one unit, be it in Florida or Texas on our travels.

My 2015 Greyhawk had that tan fiberglass, black/grey decals, and cream colored roof. I really think that was working against me as opposed to white fiberglass and the white roof. I could easily put my hand on my white fiberglass in full sun, but that tan sure could be hot. I’m positive that wasn’t helping things, so exterior color would affect your opinion on the matter, perhaps.

What is the CCC of Greyhawk 29MV with 2 ACs?

They vary widely; for reasons I’ve never understood. The last MV I saw was not a Prestige, had no second AC, and came in at 1478 pounds.

My 2015 had ~2100 or so. Go figure.

1500lbs ccc: not usable.

The only class C(30+ feet) with good ccc I have found so far:

Jayco Redhawk 29XK: 2700 lbs ccc.
Entegra Odyssey 29K: 2400 lbs ccc.

They have only one AC. Redhawk: TPO roof, Odyssey: fiberglass roof, heavier.

IF it is too hot, one AC could not cool it down. any solutions? portable AC?

I think @craigav has the most remediation you can do. Look for sites w/ shade. Hope for the best?

Portable ACs are very inefficient. But that's all I could come up with last year to stop us from baking to death.

We live in Texas. No way one AC will work. Going up to the north might be ok if staying away from warmer areas. We bought Jayco because the second AC was a got to have for us. One is marginal for anything over 30’. Good luck


Enjoy the journey

What is the BTU of the portable AC in the picture? How to put the duct through window?

Some on amazon have 14000 BTU and claim to work for 500-700 square feet. How many square feet does a 32 feet RV have?

Considering 32' long and 8' wide 32x8 would equal 256 square feet, although inside an RV likely would be a little less than 32'. ~CA

So one AC 15000BTU should work well for a 32 feet RV. everything depends on how hot outside is.
