Vent fan thoughts

Since I got the ARB fridge and summer is fast approaching (well, maybe, it snowed here the two days prior...) I know that inside temps are going to start going up in the truck and the cooler I can keep it in there the more efficient the fridge will be since the lower the ambient temperature the easier it is for it to dump the heat off the condenser coils and the less work it has to put in to keeping the temperature inside where it needs to be since it won't heat back up as quickly.

I know aside from using a reflective sunshade for the windshield (and now that I think of it the back windows as well, at least when I'm parked, which I think I can make my own using some reflective insulation I got from someone) the next best thing to keeping inside temps down is venting the air out which will draw cooler fresh air in.

To do that I know you can buy fans that fit in your windows and whatnot, but that's a nuisance I think plus if it rains or the wind blows you could get junk in your vehicle. So a thought I have is to install a fan at the back vent in the rear cargo door to push air out and fresh air should come in through the front HVAC system (provided of course it's set to outside air, though I don't know if when you turn off the vehicle if it moves it back to outside air if you had it set to inside air).

Any thoughts on doing something like this? I know it's not going to be as effective as a fan at the top of a window which will draw the hotter air out, the rear vent is kind of low in the vehicle, but it's going to be better than nothing.

I run a fridge in the back of mine and with the windows tinted and a front reflective windshield cover the interior temperatures are really not bad enough to need to add a fan or extra vent. I also would have pro's and con's to adding anything that would drain my batteries faster.

You could use vent shades an leave the windows down a inch on each window and the rain wont come in. But it will let the air flow with no battery drain.

Been running 2 ARBs(one as freezer, second as fridge) for years out in desert and I have never seen any issues.
it wil run more with higher ambient temperature and lower setting so battery drain will increase.

I think it might be easier to upgrade your battery or hook up a solar charger and controler

This would be in addition to solar and a house battery. One thought is to run the fan off a small solar panel so then it has zero effect on the battery, and it only needs to run when it's sunny out anyway.

The added benefit if it works the way I'm hoping is then you don't have a boiling hot vehicle to come back to.
