A tag axle is rated 34K in combo with the drive axle, the 20K limitation is for a single axle only.
You can get the 34K weight in any combination of the two axles, and the 20K is almost always exceeded on the drive._________________________________________________________________________
Al; You would be correct if it was a full equalizing tandem. I believe that tag is a 10 thousand lb axle. The weight law on each equalizing tandem is 33600# plus the steer axle not to exceed 80000# Upon entering the OH and PA Turnpikes you will not be allowed to enter if any axle exceeds 20,000 lbs. You are weighed automatically while collecting the ticket at the gate. If you are over you will pulled onto a set of axle scales, If still over you must exit right there.

Not to butt in but,
This came right off the Ohio Turnpike website.
Q. What is considered an overweight axle?
A. Any axle over the below allowable weights:
Single axles (axles spaced 8 ft. and over) - 21,000 lbs.
Tandem axles (spaced 4 ft. or less) - 24,000 lbs. for the tandem (12,000 per axle)
Tandem axles (spaced over 4 ft. but less than 8 ft.) - 34,000 lbs. for the tandem (17,000 per axle)
(Tri-axles: same as for tandems, depending on the axle spacing, either 12,000 or 17,000 per axle)
I'm very interested in this thread as I have approximately the same problem with virtually the same chassis.

Is there a calibration of how much weight can be shifted for
each psi eduction on the tag air bags. It is currently set at 29psi
Like TennStud says, if i go down to say 24psi, what can i expect the
steer axle to loose approximately.
------------------------------------------------------------------------------- A truck stop in Baileyton, TN let me play with their CAT scales for 1 buck per pass after the 8 bucks to weigh. I will have to find my scale tickets to be exact, As I remember 16 psi got the steer axle within limits. Which I tried, But each time I would use the service brakes the tag axle wheels would lock. I increased it 1 pound at a time until I got the tag to stop locking the wheels which was 21 psi. I then tried it under hard braking conditions I went to 23 psi and the tag will still lock under very hard breaking but I can live with that. I was still unable to get legal axle weights. During which time I was in a heated contest with Monaco due to weights. If you read your manual you will find that Monaco tells you that your coach is to be weighed with full fuel and fresh water only 1 person (driver) not to exceed 180 lbs Then the weight distribution is your responsibility. That is nothing in the bays, No personal belongings, Nothing in the grey or black tanks and no passenger. I cannot divulge the out come on this forum. I changed to the highest rated tire I could find which was Michelin 315-80-22.5 rated at 9090 lbs each on the steer axle. I don't like blowing front tires. I want the steer axle to be the least overloaded. I now have 18000+ miles and no weight or tire problems, But I am still over the axle weights. I have been told that Monaco was going to move the fuel and fresh water tanks aft. Some of you 07,08 and 09 Three axle drivers can confirm, Are your fresh,fuel and propane still just behind the steer axle??
I can remember getting in trouble on the OH Tpk. with a tour bus. It was a 45' Van Hool and when we went over the scale we got pulled over because we were overweight. The employee had all the passengers get out and then we went over the scale again. When we were then safe he said to go on. I asked about the passengers and they were told to get back on. I guess it satisfied someone to do that. I thought maybe they should just hold their bags on their laps for the rest of the way home.
I have a constant problem trying to drive with a full fuel tank. For some strange reason it always goes down, fast.

My 07 Navigator still has the fuel and propane just behind the steer axle, but the fresh water tank is back just in front of the load axle. I believe I saw the newer ones have moved the fuel and propane back another bay.
The federal regs say nothing about equalizing tags, just the spacing ,over 48" under 96" the 34k applies, Why cloud the issue with front weights? as long as it is under 20K you are good.
BTW, the Ohio turnpike is grandfathered in @21K with an allowance of 500 lbs for margin. The lights won't come on until you exceed 21500lbs.

My 2006 Exec has a solid front axle, rated @15600 lbs.
So, you are correct.

Gross Weight—The weight of a vehicle or vehicle combination and any load thereon. The Federal gross weight limit on the Interstate System is 80,000 pounds unless the Bridge Formula dictates a lower weight limit.
Single-Axle Weight—The total weight on one or more axles whose centers are spaced not more than 40 inches apart. The Federal single-axle weight limit on the Interstate System is 20,000 pounds.
Tandem-Axle Weight—The total weight on two or more consecutive axles whose centers are spaced more than 40 inches apart but not more than 96 inches apart. The Federal tandem-axle weight limit on the Interstate System is 34,000 pounds
An equalized suspension system is provided for the trailer of a trailer-truck combination of the tandem axle type, and which is mounted on each side of the trailer near the rear thereof. The suspension on each side of the trailer includes independent semielliptic leaf springs mounted in tandem relationship one behind the other, and which are respectively connected at their midpoints to the front and rear axles of the trailer. The remote ends of each spring are supported in respective brackets which, in turn, are secured to the frame of the trailer. Two equalizer support brackets are provided between the adjacent ends of each pair of springs, and two bell cranks are respectively supported in the equalizer support brackets. A tension bar intercouples the bell cranks. The adjacent ends of the springs are supported on bearing pads which are pivotally mounted in shackles. The shackles, in turn, are pivotally mounted to the respective bell cranks.-----------------------------------------------------
My interpatation is that a tandem axle has to be equalized at the center point between the 2 axles that transmits the weight to the road to qualify for the 34000# It used to be done with equalizing the spring pressure. Today it is done by equalized all air bags. The tag axle on your MH does not comply with tandem laws as it can be individually load adjusted Plus being a single wheel 10 thousand rated axle does not qualify as a tandem
