plumbing layout

Does anyone have a diagram of plumbing for the 3210? We had a hard freeze here in Dallas that lasted a few days and I have what appears to be one small leak. I will have to repair it but want to get a ideal of the plumbing layout.

I would also like to have a schematic of the typical water line layout for my 3400RE.

I took as many precautions to eliminate the lines freezing but to my dismay I had my water line freeze for two days.

I am not complaining. I would like to get into the belly of the trailer and insulate the water lines. I would also like to know where the tank dump lines are located. Many of us have water leaking or settling in the dump lines and I would like to insulate them and maybe attach a heat tape to keep them from freezing.

I don't mean to hijack landp's thread but I am also interested in this information.

Thank you
BC
