downsizing - need advice

[travelingcat]

After many years of traveling in a fifth wheel it is time to downsize. We are looking at a Winnebago Aspect. We spend summer in Florida to be near our grandson. Will the single air conditioner keep the coach comfortable? Any advice to help us with our decision will be appreciated.

If you end up with a 30ish foot Class C a single 13,500 BTU AC is going to struggle to reduce the outside temps by 20 degrees. In this scenario the question quickly becomes: How hot will it be where you are? Keep in mind that the misery index will rise dramatically with the humidity.

There are a number of tricks to help your AC. Chill the coach down early in the day. At Zion in June it was 100+ degrees every afternoon. We kept the shades pulled, a sun screen in the windshield and the curtain separating the cab from coach in place. Our 13,500 managed to keep our 24' C a pleasant 75-80 but it was really working.

I would not buy any C over 27' that only had a single 13,500. A 15,000 BTU unit will be better and anything over 30' really is getting into the two (13.5's), range.

Permit me a little misdemeanor thread drift and bring up the other side of the equation: heating. Before you buy, consider the size of the furnace, number of ducts and their location. I have seen a lot of rigs with woefully inadequate heating. Our 24' C has a 35,000 BTU, 4 duct (they are down low just a few inches above the floor), monster that keeps us toasty in any weather. Also know that the DC fan on your furnace will be the biggest load in your coach. If you don't have at least a pair of decent batteries your furnace run time will be limited. Also, furnaces burn a lot of propane so be sure you have sufficient capacity. Small rigs with LP generators typically have a very limited supply of LP when off the grid.

If you cannot be comfortable in just about any weather using your coach will not be fun.

As always.... Opinions and YMMV.

It depends on how big the Aspect and what "comfortable" means to you.

My similar construction Spirit is 30 foot, all white (not painted like an Aspect) and has a single 15K BTU air conditioner. On hot humid days it the shade, the A/C can pull interior temperatures down to 20-25 F below what it is outside. Thus 80-85 degrees on a 105 F day.

But in full sunlight, I might not see temperatures much below 90 F, from about noon to 3PM, when the lowering sun starts reducing that part of the heat load.

The second part: when it is that hot outside, I find 80-85 F comfortable. It is the temperature at which I also keep house in summer, when temperatures rise into the hundreds, and where I kept the house in summer when I lived in central Florida.

My M-I-L liked to cool her house (in Michigan) down to 70 F, dressing for winter year round. She would not be comfortable in my house or motorhome. Kind of funny, because she grew up in Louisiana many years before air conditioning and did not think of the 80s as hot until she lived in the North for many years.

You may need to add an oscillating fan to move the cool air around.

Based on my own personal experience, a single AC will do an adequate job on a typical rig up to about 28 feet long in a hot and humid environment. Any larger, and you probably need a second AC. Of course each rig has it's own peculiarities such as insulation type and thickness, single pane/dual pane windows, etc that come into play.

We just downsized from a 41' toy hauler fifth wheel to a 36' Class A gas. Ours has one AC unit. We are in Oregon where it is hot only for one week out of the year. But, we are heading to Phoenix and Dallas in the spring and summer so we'll find out if one AC is enough.
