The two solenoids at very back are the raise solenoids, the two in the middle are the dump solenoids, and the one's closest to the firewall are the travel solenoids.
One of the travel solenoids not opening is going to cause all kinds of grief when in travel mode. First thing to check, is the soleniod getting power. With the key on, and in travel mode, unplug the Packard connector for the offending solenoid. You should have around 12V on the connection coming from the coach. If you do, then replace solenoid valve. If you don't, we now have to find out why.
In the HWH system, all four travel solenoids get a postive 12V signal from a common terminal on the control board. So, the fact that one of the travel solenoids is getting power tells us the board is functioning properly.
While you are testing this out, might be a good idea to test the front ones too. PLEASE put a crib or support under the front when playing with the system. We don't want to have a flat guru.
