Gordon,
The solenoids in the inner frame are only used to lower the tag pressure using the dash toggle switch. One solenoid blocks the common air bag pressure and the other exhausts the air from the tag tank. The inner frame rail solenoids are not energized and have no effect on the travel or leveling mode--that is done strictly through the 6-pack. The 6-pack system is part of the HWH leveling system, the inner frame rail solenoids are not. Without the inner frame rail solenoids Newell had no way to isolate the tag tanks or reduce the tag pressure. Remember in my coach Newell only advises using the tag switch to shift weight to the drive axle for scaling purposes. I have never used the switch.

I hope this offers some clarification.....................
