Which fitting are you referring to?
The drain plug on the outside, or the hot water discharge on the inside?
Any chance of pics of the fitting you are talking about?
Is the tubing in the camper gray or blue and red? This helps tell us what type you have.
Here is the blue and red tubing of the newer Pex. Are you after the white 90 degree elbow on the bottom or top as shown in these pics?
The size in these pics is 1/2" Pex tubing. Coming out of the top of the HW heater is a 1/2 NPT check valve that then screws onto the white female elbow which has the thread pitch like 1/2 NPT but is not tapered, it is straight running thread and has an inverted chamfer inside so it can seal on that chamfer. see below
The inverted chamfer looks like what is in this pic.
If all of your tubing is gray, that is a little bit different then the newer PEX
