Funny you should ask.. I have been pondering doing exactly that for some time since I never use the blasted thing. I don’t know about a “proper procedure” but it seems like it would be pretty easy to do.
You can use a plug on the gas flair fitting. In fact my
Scamp 16 model 4 came with an unused copper
propane line about 1-2 feet long, with a plug, right next to the water heater. The gas line came off a tee that also had gas line feeding the water heater and
fridge on the starboard side. I assume it was a pre-made multiple gas line that was designed to also connect to the stove in campers that had one on that side, but I really don’t know why it was there. The same plug would work in the gas line for the heater, after it is removed from the heater. No cutting would be needed although the pipe should be well secured and of course leak tested.
The plumbing can just be cut and capped off on the supply side. As it happens,
I did just that (cut and capped the inlet water pipe because I had a leak in the shutoff valve). I don't think a plug would be needed on hot (red) side since the hot water piping would then be unused. But just to be safe in case I would plug it. There might be a chance that the shower faucet could develop an internal leak from the cold to the hot side.
I guess the “proper” way would be to use a Propex expander with a plug and Propex ring. I just used a Pex plug with copper ring that I got at the local hardware store. You need a special crimper for that but they are much more common than the Propex expander and you can likely rent one if you don’t want to buy on. Both tools are hard to use in the tight space but once the water heater is out there would be plenty of room.
The water heater frame is riveted to the body (shell) along its perimeter. Just need to drill the heads off the rivets and remove them. The heater sits on a board on top of the wheel well and should come right out.
Now my question is, what do you plan to do with the resulting ~18x14 inch hole in the side of the camper? You could patch it with
fiberglass, or add a hatch door. I found that standard size marine hatches don’t fit so you would need to deal with that by enlarging the hole or making it smaller. Or you can
buy a custom sized hatch door that would require careful measuring of the hole, but no
fiberglass work, unless the curve of the shell is a problem. Its not cheap however.
