When Driving During the Summer How Many Roof Airs Are Running
#1
All,
When driving during the Summer with the generator running how many roof airs are turned on? In late May I used roof air number 1 for seven hours and stayed comfortable, but last week tried the same routine and the temperature inside the Newell go to 85. The day I was traveling the outside temperature was in the mid 70's. Looking for suggestions. Thank in you in advance.

Reece, In warm weather, I run the gen so I can run my front and rear A/Cs. I want to load my gen as much as I can so both A/Cs seems a good thing to me.

Reese, although I don't have roof airs, I leave all the thermostats set for about 75 degrees when traveling and let the A/C's turn themselves off and on. When it is really hot outside (like 118) all 4 AC's will be running most of the time. At the mid 70's outside, only one or two will typically be on at any given time, but I just let the thermostats sort it out.

We roll like Michael. Turn them all on, and let the tstats sort it out.

There are couple of tricks we have developed to keep the coach comfy while traveling in hot weather (aka this entire summer). One, while driving, I set the front AC fan to run all the time. It circulates the air and minimizes temperature swings. Two, we run the rear AC tstats three to four degrees cooler than the front. It keeps the engine heat from saturating the rear and makes the coach more comfortable when first parked.

Running the generator with a load is far better than just lightly loading it with one AC, as Rudy said.

My wife does NOT like to be hot. Happy wife = happy life. Even if if means wearing a long sleeve shirt while I drive.

I run all my Dometic basement a/c as mentioned above. The rear one will not run the fan all the time. I havent been able to figure that out yet...

Without dash air my Newell gets hot in the front . Originally the Salon HVAC dumped out just over the entrance door. During the remodel I added a duct behind the valance it to the front of the salon area after removing the fluorescent light fixtures. The new LED lights fit in there as well. My coach had two HVAC units serving the 8 bunks in the middle of the coach. After removing six of those bunks I ducted one of the middle HVAC units to that area over the door to assist in the salon area.

ok, a desert rat from phoenix has to weigh in. hot is relative. if it is 90 or below that is almost winter and i can get by with just running the dash air (which blows very cold once i fixed it). if it is 110 plus outside then all 4 airs are on with the genny.

I have three 15k roof airs and I usually just run the front two on low or medium, this fat boy don't sweat.

I need to fix my dash air like Tom, it is on the list.
