Steep Drive Ways

A while back I pulled into a parking lot that was just a bit steep and I drug the front end a bit and again when I pulled out another drive.  :o

My question is that if I see one that may be questionable can I hit the raise on the HWH to pick it up.

Will it go back to travel mode by itself?

Thanks

It has been a while since we had our coach, but that is what we did all the time with steep entrances and exits as well as high railroad tracks.  We held the button in to raise the coach and when we let go, it went back to travel mode.  Now our coach was a U320, so not sure all worked that way.  It should tell you in your HWH book.

Thanks juicesqueezer, I will have to remember to look at my book, I keep them in the coach and it is stored 40 miles away.

On my '99 the second I release the brakes the air dumps to ride height. I have found that backing out my driveway I can leave the parking brake on and power out with the coach raised. Coming in it drops faster than I can get up the apron. I have seen posts where other members were able to move with coach raised.

On some coach year models, the "RAISE" button is momentary - only works while you hold it down.  On others, it is a "latching" switch.  I don't know which years had the latching switch.  Pretty easy to do a simple test to determine which you have.  Paragraphs below come from the HWH Leveling System Textbook, Page 19-20:

When a momentary "RAISE" button is pushed, a +12 volt signal is sent to all raise solenoid valves in the system. The red AIR LEVEL light will come on steady. The red RAISE light will flash. Air will be added to all the air bags, raising the vehicle. When the "RAISE" button is released, the raise solenoid valves will close. The indicator lights will go out. If the ignition is off, the vehicle will stay in the position it was when the button was released. If the ignition is on, the system will return to the TRAVEL mode and the vehicle will return to travel height. If the touch panel was on when the "RAISE" button was pushed, the touch panel will turn off when the button is released.

When a latching "RAISE" button is pushed, a +12 volt signal is sent to all the raise solenoid valves. The AIR LEVEL light will come on steady. The red RAISE light will flash. Air will be added to all the air bags raising the vehicle. The vehicle will raise as far as it can go. The touch panel and system will stay in the RAISE mode when the button is released and the vehicle will remain in a completely raised position. The panel will stay in the RAISE mode until the "OFF" button is pushed or until the vehicle speed exceeds the speed switch setting (normally 15 mph).  The system will not return to the TRAVEL mode and the vehicle will not return to travel height until the "OFF" button is pushed or the vehicle exceeds the speed switch setting.

Thanks rbark, mine must be the momentary.  when I was putting the spacers in the frame I would raise it all the way and jump out and get one in place but before I can put another in it would drop so i would run back and raise it and do the next one.  Heck I got tired just putting the spacers in "LOL"

Steve,

Getting back to your original question, even if your coach has the momentary switch, you can still use the "RAISE" function to jack the coach up when driving up or down steep inclines, over "high-center" railroad tracks, etc.  You just have to manually hold the button down to keep the coach raised.  The only restriction is that you must proceed slowly (5 mph or less) while the coach is jacked up (or lowered, as the case may be).  Raising the coach to max height puts the drive shaft at a extreme angle, and can stress the U-joints.  So, it's not something you would want to do all the time, but once in a while won't hurt anything.  Just use good judgement.  Another excerpt from the same manual I linked above:

The "DUMP" and "RAISE" buttons are provided to allow the operator to raise or lower the vehicle while the vehicle is moving short distances to avoid an obstacle, such as lowering the vehicle to get into a building.

CAUTION:    The vehicle should not be moved at speeds in excess of 5 m.p.h. unless the vehicle is at the proper ride height. It is the operator's responsibility to check that the vehicle is at the proper ride height for traveling.

I tried that on mine, when I released the brakes it still went down. They must have made a change in the '99

Moving coach with rear raised too high can damage output drive seal in Allison transmission due to high drive shaft angle. Would be pretty cautious on that approach.
At least that was what I was told
