Obviously something ( propane or carbon monoxide ) is leaking inside the unit either while water heater is running or after. I hope I don't need to warn you how dangerous this can be, and that you should have it checked by a qualified technician A.S.A.P. , and propane should be shut off until such.
With that said, 3 things come to mind that should be inspected or considered. Look at where propane line comes through housing of water heater and attaches to gas valve. There should be a rubber grommet in the hole and it should be air tight so as not to allow any fumes or gas to enter back inside trailer. If it's not air tight, use a silicone type sealant and seal it good at that location. Another thing I would look for is any window or opening above water heater that may be allowing fumes or gas to enter inside trailer. Next, I would take a spray bottle, fill it with water and squirt some liquid dish soap in and mix it to test for leaks around all fittings at water heater, and especially spray orifice where gas comes out of valve and enters burner tube, when heater is off, to see if any bubbles form at end of that orifice, which would indicate a leaking gas valve. Again, I urge you to have it checked by an experienced technician for the safety of yourself as well as your family and friends.

SOURCE: I have an Atwood electronic
Use a multimeter or test light for 12volt DC, and check at gas valve for 12 volts when it is trying to ignite (you here/see it sparking ). If no 12 volts to there, it will not ignite because no gas is flowing through valve. Try removing the connectors on the circuit board/module ( with switch in off position ) and cleaning the board contacts with a pencil eraser, and spray WD-40, or preferably an electrical spray/contact spray on connector contacts and retry. Board, or module may be located outside , or inside on top of tank, depending on what year and set-up. If that doesn't work, there is a small cut-out enclosed in plastic sleeve right near pressure relief valve area, that looks like a resistor that may be faulty. Remove it from the circuit and try it then. Simply pull the wire off at thermostat, pull that out of the sleeve by disconnecting it from the female spade connector, then put female spade where it used to be on thermostat terminal. If it works, buy a new thermal cut-off. If all that is done and tried, and still doesn't light, replace module.
