Fan-Tastic Vents - Worth it?

[LucyImHome]

The vent/fans that were in my mh were toast from the so cal sun, literally crumbled when removed. I replaced them with the basic Fantastic fans. They worked great for the year I had the mh. Now I have a TT. Same situation with old crappy vents. Replaced with the same Fantastic fans. The one in the front blew out the circuit and haven't been able to track the problem down. The one in the shower worked great through the summer and fall, but as soon as the rain started, it quit working. I don't blame the fans. It's an older TT, '82, so who knows what's up with the wiring. I'll figure it out when it stops raining. Or not. lol
