If I were to say yes it would be a guess.

However, the automatic system that dumps air on my coach along with the stabilizators that keep the rear from dropping when my wheels are turned to the extreme, left or right works, and because of that I do not need to manually lift the tag. If I were to manually lift the tag the stabilizators would not function and the rear would drop until the drive axle air bags were filled with air to raise the rear to the normal height.

Most Prevost techs are not familiar with that system that was designed for and used on early 45 foot coaches to minimize tag axle tire scuffing as an alternative to the "steerable" tag axle that was supplied on MCI coaches around that time. I think that feature was discontinued and it is my understanding that some converters even went so far as to disable the system if the coach had it installed.

Aren't you glad you asked?

See you guys in Kerrville, where I hope Ed allows you in the bed instead of the fiddle.
