Keeping parked vehicle cool

[bobsrv]

My class B is parked in my driveway in Tucson. I do not use it as much as I would like right now so it is sitting in the 100plus temps so it gets pretty hot inside. I do have a couple windows cracked but can't open up anymore. I also have a sunshade in the front window and all the curtains shut. Suggestions for keeping it a little bit cooler inside? I was thinking of trying to set up a solar fan but I have yet to find one that got a decent review. Have a feeling there's not much I can do but thought I would throw it out there just in case.

It isn't cheap, but I'd replace the vent fan with a Fantastic Vent, one that has a rain sensor, or ideally, a MaxxAir fan that works with a vent cover on it.

Then, open a few windows, set the fan's thermostat, and let it do the rest. To keep it powered, one can plug the van into shore power, or see about adding a solar panel or two to offset the amp draw of the fan. One benefit of a solar panel is that, due to the air gap between it and the vehicle, it provides shade.

Of course, the ideal solution is a carport, but a high flow vent fan can help.

For my TT that sits in the sun, I use reflectix in windows and have trailer plugged in. since I have 30 amp available, I set AC on about 90. Prior to having 30 amp installed, I would still plug in and run vent fans.

The vent fan will push air out, and help a little, but fans themselves won't cool the air.
Without a carport of some type, tarp, etc, try covering the windows with Reflectex, and park on dirt, or grass.
I also live in Tucson and would see inside temps of my Roadtrek at 125 or more, with the windows covered. This was the reason I decided to go with a TT, and build a garage.
I mean with 105 today, and 109 for the rest of the week, only so much you can do. Pray for the Monsoons to start and cool things off.

Can you run an extension cord from the house, so you can run the vent fan continuously?

Also---if you could rig some sort of shade shelter over it, that would help tremendously.
