Has anyone installed an exhaust fan in their shell? I'm thinking about putting one of the smaller Nicro solar models. I'm not totally adverse to drilling a big hole in my fiberglass shell, I'm just curious if anyone has a better idea. The small fan will move a lot more air than I need to worry about for the bed of the Tacoma so I'm a bit worried about feeding it (I have a tailgate seal in place but the rest of the bed leaks air and dust pretty badly) as well as dust.
