Keeping cool

Sorry, my link does not work. It is a maxair roof vent cover.

Absolutely...... Ask me how I know.......

If you want to drive down the highway with them open I would recommend something like this :

In really hot weather I run my generator and roof air. It's a fifth wheel so hopefully dash air.

Not if you have a vent cover over your vent lid. They are designed to let your vent lids open all the time.
I would suggest getting the Maxxair covers,they will make your vent lids last longer.

The covers are constructed of high density polyethylene with maximum UV inhibitors for years of worry-free protection,unlike the others on the market today plus a 6 year warranty.

If you’re asking about cooling as you go down the highway, open only the rearmost roof vent and set the dash A/C to point as many vents as possible straight down the back with the fan on highest setting.

Do NOT set it to ‘max A/C’ which will close the air intakes and defeat the point of the rear roof vent being open, which is to vacuum hot air out and replace it will cooled / dehumidified air.

A Ford E-series dash A/C system is nearly as much cooling capacity as 2 rooftop units.

If you have a proper thermostat for the air conditioner, just set it to the temperature you want; it won't cool down faster with a lower thermostat temperature setting.

What I generally do when driving is use the vehicle air conditioner and have a rear ceiling vent open (one with a vent cover over it) to help pull the cool air through the vehicle. The truck air conditioner is theoretically a good bit more powerful than a roof air conditioner, though it's somewhat limited by what sort of airflow you can get through the coils (and not helped by having the ductwork directly above a big hot engine). I think it's somewhere in the vicinity of 25,000 to 30,000 BTUs.

Upon arriving at a camp site, if the interior of the RV is hotter than the outside air, opening the vents and windows will cool it down rather more quickly than an air conditioner can. I'm not sure running the air conditioner during that time has much bearing on things; the basic goal is just plain old air exchange. Maybe runnign the air conditioner's fan would help in some cases.

I love a cold RV when sleeping.
