Props to Valterra valves

[Texan]

Thanks for all the info guys. I know the black tank has the 3'' outlet but does the gray tank also. My gray and black tanks are in the front and run side by side. I know valterra has 1 1/2'' and 3'' valves and want to make sure i have the correct ones.I will go ahead and order the 72'' cables so as to have enough cable.

That is correct. Because the valves are opposing each other the gray tank cable must be longer. I believe 72" is the longest you can get in a kit. I ordered 2-96" for the front 2 tanks (because I was not sure what would be needed) and trimmed them to fit nicely. For the galley tank I ordered a 120" cable so I could move it forward out from under the slide to one of the extra mounting holes in the center level up leg bracket.
