The time when you are correct, is when I pull the trailer with a 1500# tongue weight. In that case, I generally inflate the tag between 10-15 mph. After checking with the manufacturer and tire people, I'm confident that it's acceptable.

I understand your point and agree to some extent. Our MH tires will rot before they are worn out, so scuffing around a turn probably does not matter. I got to where I am because initially the steer axle was carrying more than the drive axle. Replacing the proportioning valve with regulators allowed me to get a better distribution of weight between the axles. One thing led to another and now I have control over how I manage the load. Probably not needed by most, but I feel better about it.
interesting, my tags come up off the ground, completely.

I think that tags that lift entirely off the ground is not the norm for most production MHs. There is some concern that the tag weight transferred to the drive axle could be damaging.

that's the idea behind lifting, every tag Monaco coach with s chassis lifts or is capable of lifting tag off the ground , that's the way they are designed and there are more Monaco tags than any other I would guess and they have likely made more tags than anyone else. If ya cant unload them what is the use?

When your tag is up or the weight taken off, that weight and some front axle is transferred to the drive axle. In most cases, this puts more weight on the drive axle than it was designed for and more weight on the drive tires than the are typically inflated too. This excess weight is not a big deal when maneuvering at parking lot speeds. Is running at 19 mph for long distances too much on the over weight drive axle or under inflated drive tires? I don't know, but wouldn't do it.

To each their own and FWIW I seldom raise my tag. Yep, I know I scuff the tag tires doing so, but never wear out the tread anyway before the tires are replaced.
You are correct, the Main rear is being overloaded by both, the Tag being lifted, resulting in un loading the Front axle AND extending the rear "SWING" of the Coach there for making it squirrely at a higher speed and can't be compared to a the way a 2 axle Coach handles.
