Well I've been snooping around the pages for a while now. We finally broke down and bought a new HW31SCTH. We are itching to take it out but the weather in the north east hasn't been very favorable. We have made a few changes already. We ditched the double gray and black water drains and combined them into one drain. And added a Hott Rod water heater kit to the trailer. That was a bit of a pain wiring it though the slide out but I got er done. I'm sure I'll find more stuff to do with it later.
