My Willie forced air heat is great forthe front seaters. Yep, it is a 12volt fan run off a tiny 12volt battery in the passenger seat storage in stock configuration. You could simulate it with a low power fan in a small duct mounted to the underside of the platform and hook up the wires add a switch and fuse and you'd be done. The biggest issue is finding the 12volt fan. BTW, the Willie version is a shallow box under the platform. I'd make sure the wires are in a protective sleave.
