I did have one made by a company that specializes in these. It's been a while and I do not have the paperwork. My coach did not have the propane leak detector under the couch by the furnace, so I had this new constant duty valve made and added a manual shut off switch next to the row of lighting switches as you exit the coach. It is lit to remind you it is on. We generally shut off the solenoid when we leave unless the heat is running.
