I have an '88 Starcraft with 1 LP tank mounted on the tounge and a Marshall 290 2-stage regulator. The tank sits so close to the camper that the regulator is getting tweaked and it's actually wearing a hole on the siding. I'm afraid the regulator is going to break off at some point. My question is can I swap the 290 for a smaller regulator (Marshall 230)? The way the tank mounts prevents me from simply rotating the tank.
