Out of curiosity I hooked up my OBD to see what the fuel flow was on my 8.1L Workhorse at idle, which hovered around .72 gph, and then turned on the AC and it jumped to about .83 gph. Now this is at idle, so I have no idea how that would translate to the increase while driving. Perhaps some knowledgeable folks here would know.

I will run the dash, the gen, the roof air, even a cooling seat cushion on ours to stay cool - which IS the point in the south

The reason I have a m/h is that I spend so much time on the road, and unlike tourists, I do so summer and winter.

I spend a lot of time in 'da sowth', south Florida in particular. That's why I have gotten so good at keeping the coach cool.



I have to chuckle about people with a 43' Class A participating in a Class C thread about cooling and trying to explain to the OP, who has a 26' Class C, what to do to stay cool..........

That way we should be able to keep the cool air in the front of the coach.
I normally just run both A/C units. If I'm already running the generator, what's the sense in only trying to run one. As somebody said, These aren't an economical mode of transportation anyway, you may as well be comfortable.

Also, running both A/Cs allows them to share the cooling load, thereby making it easier on both units.

Generators don't get run under load near enuff. You should turn everything on that you have so as to stay cool. You can also hang a sheet behind you to help keep dash air confined. I go through Redding in August. 105, 107, it sux. Staying cool is cool and gas is cheap!

I didn't mean to imply that you couldn't help friend, but poking fun at us 'nord'ners' about staying cool advice (whether we're Yankees or from Cannuckistan) is about as silly as implying that because the dash A/C on a 43'er doesn't do much it means that on a 24' or 26'er it won't do much either.

BTW, the dash A/C on a Ford Class C chassis has more theoretical cooling capacity than 2 rooftop units.

Sprinter chassis is terrible in that the recirculate only works for about 10 minutes and then automatically shifts back to fresh or outside air. You have to keep pressing the recirculate button over and over again, or wire the damper in the recirculate position.

I had the same issue on my 2015 Sprinter chassis. Drove me nuts. I just had it in for service at MB and they reflashed the unit and replaced some regulator. I'm told it's fixed now. We're leaving for Yellowstone tomorrow, so we'll soon find out.

On the OP topic, the Sprinter chassis AC easily cools the entire 25ft coach. I only run the genny and coach AC if we make a long stop to keep everything nice and cool.

Because i always travel.with dogs I run the genie and house AC to keep them comfortable. I have 29' C and i shut the door that separates the bath/bedroom area from rest plus draw my privacy curtain across cab area. If I get hot i hit my dash ac as well and then open the privacy curtain.

Ive never noticed an overall MPG change doing this or in winter . I get a pretty consistent 7.5 if i Go 65 and 8mpg if I go.60...

Another thing I didn't see mentioned, eliminate / reduce the sources of heat.

I got the idea of reducing sound and heat coming from the engine cover on one of the Class C forums. I added insulation to my engine cove, and it made a big difference in heat and sound coming from the doghouse cover.

ALSO - Tinting windows will help keep heat from coming in:

Ok, If I open the rear vents and use the chassis ac, should I use the privacy curtain also.

One more thought.

As I drove my MH yesterday in southern NM (we hit 108 in the afternoon), I was wondering which would be best. My concern at that point was straining and/or overheating the engine. Turning the cab AC off significantly reduces the operating temperature of the engine so using the coach air makes a lot more sense at that point.

Shut the Cab A/C off and run the Genny ! That's what it's for ! During the Summer-- The Hot months my Genny Runs from the time I leave my driveway until I return a week or 2 later. Non stop most of the time.!

Open ONE rear roof vent, run the chassis a/c on highest fan setting but NOT on Max a/c, with the privacy curtain open and the center dash vents pointed straight down the middle of the coach.
