I'm new here. I just picked up a 1986 18ft Toyota Sunland Express. In the state of Ky I have to have it inspected by a fire marshal. I have a carbon dioxide detector, fire extinguisher, and smoke detector, but I cant locate a a Propane detector on my rig. Dont know if it originally came with one? I want to hard wire one in, but I'm not quite sure where to do so ? I know the lower the better since propane lays low when a leak occurs. My rig has the Wrap around Dinette in the back with the Frig and Stove on the left while the Sink, Furnace, Fuse Box are all on the right side. Please note this is all facing the back looking at the dinette. I did find some colored cables that were to the right of the fuse box. I'm thinking this would be my best option ? I've looked online and here for info to no avail. I'm thinking that the wiring is pretty similar for most of the RV models from this time period ? If anyone has any advice on the best spot to piggy back or wire into please advise in detail if possible. I know this should be a easy fix/install but electric work is where I always get stumped. Thanks in Advance.
