Does anyone know if you can operate a 2000 u320, in raised mode for short distances to clear ground issues
Unless it is specifically prohibited in your U320 Owners Manual, you should be OK moving the coach in the raised position at slow speeds for short distances. When coach is fully raised (or lowered) the drive shaft is at a extreme angle which puts stress on the U-joints, hence the speed and distance limitations. Excerpt below from the HWH Leveling System Text Book:
"DUMP" AND "RAISE" BUTTONS
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.
Thanks I guess I could've looked at my manual duh!
Just one caveat. When you raise to full height you use a lot of air and you may get down to the alarm level. In that case you have to wait a bit to let it build back up before driving on.

Kind of an aside, Country Coach RV owners manual reccomend under air leveling, airing up to the max in heavy wind conditions. It never made sence to me, but it was in their manual.
If you are on level ground the full height max pressure locks the coach fully raised and decreases the wind induced body motion. You could drop the coach fully down but the internal air bags "bumpers" are fairly soft and the coach would still bounce I remember
