Rusty Kramer

Yes Rusty its 9 1/2 front and 11 rear but you need to set it using the old procedure deplete the air in system then measuring from the top of the H frame to the bottom of the coach frame starting at the rear (2 valves) first then the front, start the coach air up to travel mode then shut the coach off and deplete coach air and remeasure.
If you dont know how to set the rideheight valve pm me your email add and i will send you a picture of how.
Dont get confused and try to use the new procudure of measuring the air bags as that procedure will not work on our older coaches.

I just received this. I am sorry it took so long to get back to you. Did you get information on the TST TPMS System you were looking for? Please feel free to contact me at 210-420-0132

Do you have the problem only with the coach hooked up to a external water source? If so you may need to put a presure limiting valve on the house before entering the coach (too much pressure without it).
