I finally got it up to a level where the light remained on.
John,

The "TRAVEL" light on your HWH touch panel has nothing to do with ride height, the attitude of the coach, or if one end is lower or higher than the other.  It is only a indication that the suspension system has reached some minimum air pressure.  In the second manual I linked above (reply #4) you will find the following explanation:

The "TRAVEL" Light. This green indicator light will only work with the ignition on. This light is on whenever the ignition is on if the leveling system panel is off, provided there is sufficient air pressure in the suspension. The "TRAVEL" light only means the leveling system is off and the air system has started to build air pressure. It does not mean the vehicle is at the proper ride height.

The signal that turns the travel light on and off comes from a pressure switch on the rear 6-pack manifold.  This switch is usually set at 85 psi.  "Sufficient air pressure" in the paragraph above, then, means "more than 85 psi".  So, if the ignition is on, leveling system is off, and air pressure is greater than 85 psi, the "TRAVEL" light should be on. 

If this is NOT the case with your system, then there is a problem, which may have something to do with communication between the pressure switch and the control box.  The light should not be going on and off momentarily - it should either be ON, or OFF.

I still think your best bet is a visit to HWH for a complete system check.  I believe I have read here on the Forum that HWH does not charge you anything for a system check.  Someone who has been there recently may be able to verify if that is true?

Thanks Chuck.  Just hoping I can get it to stay in travel mode so I can go to HWH.  I will check all connections on the control box tomorrow and see if I can locate the pressure switches.

You can pull the travel fuse and set the height manually for a temporary fix. Do a search and there is instructions and location to do this

I chased an HWH situation that defied my pay grade. (Easy) Our buddy Keith R @ MOT solved it for me: Mud Daubers built a blocking bit of stuff on the left exhaust port. Like these flying bugs do with propane openings, they like the manifold area. I wasn't charged with this fix by MOT.

I hope that a simple solution can help you out! Good luck. P

Yes, the infamous "Mud Dauber Plug" can certainly cause problems with lowering your coach.  Any of the ride or leveling functions that require "releasing" air from the system can potentially be fouled up by those little buggers.

For the benefit of those who don't crawl around under their coaches for fun (like I do), I will attach a photo below of a 6-pack.  The exhaust ports are the 1/4" holes drilled in the manifold, directly below the pressure switches (this is a front 6-pack).  There are 2 exhaust ports in each 6-pack (front and rear, + tag axel if you have one).  Whenever you are wandering around under the coach, it is always good to check that these holes are unobstructed.

Am I the only one who finds it amazing that a MUD plug can block the flow of high pressure air (100 psi plus) out of a relatively large smooth-bore hole?  A engineer (not me) could calculate the force exerted by 100 psi on a 0.25" diameter plug - I bet it would be pretty impressive!

FWIW;
100 psi ='s 100 psi for all intent and purpose in this situation. 
Computing pressure drop over distance, is another story.  pc

Chuck, are those labels on the air lines visible in photo your addition or are they OEM?

I find it astounding that they plug the exhaust ports... I guess it explains the strength of adobe buildings!

The yellow paper labels are mine.  When I installed the new push-to-fit connectors, I labeled all the air lines to be sure I got them back in the proper place.

Chuck, a 1/4" line (assuming it is ID) has a cross section are of 0.0491 square inches.  At 100 psi that is 4.91 pounds of force.  Those birdies are tough builders.

Not birds - we are talking about mud dauber WASPS...freaking tiny little bugs that can put the air suspension system out of service!

Just drove 180 miles to HWH with the travel light off and the dash warning light on.  No issues driving.  It was the 85 psi pressure switch that need to be replaced.  HWH checked out everything else on the coach as part of what they refer to as a free annual inspection.  Good to go for the summer.

Mark,

Thanks for verifying the "Free Annual Inspection" at HWH.  I think this is something every Foretravel owner needs to work into their travel plans, at the very least every couple years.  You have to live with the leveling system every time you drive the coach - you want it to be right!
