Rear window rain guard?

[Lindenwood]

Howdy. I am getting ready to hook up a PulseWidth-Modulating rheostat between my 2nd battery and my dash blower. The intent is to be able to operate the fan at a low setting (say, 0.2-0.5A) during the day to keep cabin heat down when parked in the sun, and to be able to operate it at more moderate settings when sleeping in the rig at night.

I already have side-window rain-deflectors, but, to get the most effective airflow I would ideally be able to keep the rear window cracked. Unfortunately, without a rain deflector that is really tempting fate!

Does anyone know where I might find one, or if one is available at all?

Thanks!

I haven't been able to find anything either

I've never seen one.

Not that it would help with ventilation while sleeping, but do you already use a windshield reflector when parked in the sun? I find that along with front window vents, the reflector makes a huge difference in interior temps. Also keeps harmful UV light from fading/cracking interior.

I do! I also have ceramic tint on all the windows, including a transparent film on the front with the same UV/IR filtering properties.

You already have a vent built into the driver's side rear panel in the cargo area. No need to crack a window.

They make 3rd gen rear window "airfoil/spoilers" that allegedly minimizes dirt sticking to the rear window. Not a permanent solution, but when you are setting up camp in the rain, you can probably add an eavestrough on top of that spoiler with earth magnets…..

This would do the trick as well but pricey: Burtman Industries

I actually contacted Jason about this, but he pointed out that it has wind ports between the spoiler and body that would let water drip in if I wasnt moving.

You know, I always thought that was more meant to minimize door-slam overpressure. But, I just tested and with the rig sealed up and the blower on there is a good breeze coming straight out of that vent! I'll just have tk be careful not to block it qhen packing or sleeping!

Thanks!

Cracking the rear hatch window will be much more effective, since the warmer, moist (from breathing) air rises. The vent below will be exhausting the cooler/drier air. It will work... just not as effectively.

Damn. Good point! #Science

If I get really seriously into the idea, I suppose I could [learn how to] fiberglas over the gaps in [MENTION=5759]jasonb[/MENTION]urtman spoiler.
