F-up on my problem (intermitent,erratic working of the touchpad, 325 series, hydraulic leveling system)......did all the Diagnostic tests as recommended by GaryKD and you all, and finally felt the touchpad had to be changed....ordered from Newmar..on-line estimate...$291 + Shipping !!
Called HWH and they put me on a call hold for 3 days........Called Stuart levelling (
HWH Replacement Parts - Stuart's Services) and got the part at $165.00 and they answered immmediately !
New touchpad installed and my levelling system works A+
Thanks !
