I found these really cool on/off remote switches.

I installed two yacht fans in the sleeper, they really move some air. https://amzn.to/2xTcMrH


They move too much air when it starts to get cooler out, and there is no way for me to just jump in the back and hit the wall switch I installed in the sleeper. So I needed something to turn these two fans off, individually if need be, going down the road...

I found this, https://amzn.to/2SdV9fh


I bought two, just wired them up in line, 3 amp fuse, both remotes work independently of each other, so no conflicts there, and they were programed right out of the box. Work flawlessly. I don't even have to turn around, I can just hit the on or off button and it is done. The key fobs, two per unit, are solid, actually nicer than the ones that came with my Silverado. The unit itself is just a tad bigger than a Zippo lighter, around 1.5 inches thick.

Hope this helps someone, they have these for 12 volt and 120 volt. The 12 volt unit is rated up to 40 amps, so you can use with quite a few 12 volt devices.
