Forward ceiling height lower in M-Class vs. Momentum?

[bertschb]

I'm trying to figure out some of the differences between the "regular" Momentum and the M-Class. Since the M-Class does not have a drop frame, does that mean the ceiling height in the front bedroom is lower?

It seems Grand Design markets the M-Class as a lighter alternative to the Momentums. But, several of the M-Class models have the same 20,000lb GVWR and a couple of them have higher CCC than the Momentums. The M-Class models also have garages that are quite a bit larger.

Other than the drop frame, I'm not really sure what differentiates the two models. Does anybody have any insights?

I think that the lighter weight marketing started a few years ago before the G class came alongrage

My 2021 398M has a 21K GVWR and a 18’ garage

The only thing I see different is the pass thru storage is smaller in the M class due to the straight frame
But that gives the M class more ground clearance
Which is important to me

I think the drop frame just gives a larger passthrough space but the ceiling height remains the same.

That would be nice. I'm just waiting for one to show up at a dealer nearby so I can check it out myself.
