I'm going to a Prevost seminar next weekend and I have a list of questions that I will get answers for.
Holstein13, as I mentioned too, our tag releases pressure but doesn't lift all the way. We have the H-3 chassis and while I was at Prevost in Nashville recently, I saw a couple of passenger XLIII chassis's where their tags lifted all the way up. I guess we are too heavy, like you.
MM.
On edit: Looking at the owner's manual, it doesn't tell me if the tag will lower on it's own. There is a audible warning if it's up and you go over 12 mph.
Our axle ratings are:
Front: 19,000 lbs.
Drive: 22,500 lbs.
Tag: 14,000 lbs.
