I copied Stan's install of the Manchester tank on the driver side. He has a good write up about it on his build thread. I used the same tank and the same install method and the tank fits great. I did put my gray water tank under the slider. I didn't really want a propane tank so close to the muffler. But with that being said I think it could be done. My gray water tank ends up about an inch from the muffler. To protect it I did wrap my muffler and exhaust with header tape which pretty much keeps any heat from coming off the muffler. As an added measurement I put a piece of heat shield material on the tank to absorb any heat. Mostly there in case something were to happen to the header tape.
