Good call on the moving blanket, we have been exploring options but we store so much in the front seats at this point, whatever we had in place would get destroyed/torn down.
To keep loads down I would try out some Eva-Dry 500's. We have 5 of them placed throughout the bathroom, cabinets, galley etc. They require no power to operate and you can recharge them when back at home. In addition, we run (2) Eva-Dry EDV-4000 (1 in the garage, 1 in the house portion). You could always run a 15 amp extension cord out from the house and keep it running when parked at home. We leave ours on when at home, just to help dry everything out.
