Replacing pilot assembly what type dope?
I am replacing the pilot light and thermocouple on a Suburban gas water heater for my pop-up camper. What type of pipe dope should I use at the connections to the thermostat control? The compression fittings are made of brass.

Compression fitting should not require pipe dope.

Okay. It looked like there was no pipe dope on the original, but I wanted to be sure.

How easy is it to bend the tubes from the thermocouple and the pilot light? Is there anything I can use to make sure I don't crimp them?

How far should I dis-assemble the original? Should I take off the burner chamber (tube)?

Just exactly what part are you replacing? What is wrong with the heater? Is it the pilot won't stay lit? If so then replacing the thermo coupler is all you will need to do.

The tube from the thermostat control to the pilot light has been pinched. It has been hit too many times when trying to remove the anode rod on the water heater during winterizing. I have finally bought a high quality socket, extension, and wrench, to do the job without the associated slipping, so the tubes should be safe from now on.

The pilot light and thermocouple assembly comes together with the mounting bracket for the Suburban water heater. Since it is for an RV, it is all kind of cramped in this area.

I was able to replace and test the assembly last night. It works great and there are no leaks.

Thanks for your help.
