UA class c of any kind with an obstruction of any sort behind the seat will all sit the same.
No matter the coach, the physics doesn't change.
The cutaway chassis is all the same dependant only on chassis brand and then I'll wager you're within a half inch of same.
At 5'8" there isn't much of a general population reason to have the seat in the place I have my 6'4" height and posture adjusted for.
With the extra 8" of leg/posture room you'll have, I'm daring to say this isn't a recline issue.
What's the worry of reclination?
Is this a posture problem?
I'm about to be very frank and speak specifically of class b and c and not specifically of the op:
If any of you all have a girth problem or a width problem, or you are infirm of balance or joint, a class b or c is not for you.
The terminally stupid narrowness to get to the rear of the vehicle is prohibitive.
You'll be going outside of the cab to get inside the coach.
You all(collectively anyone and everyone of greater girth or lesser contortion than is required of the space between those front seats, be you 5'2" or 7'2")
can take this as a slight and a guess,
Or
can take this as an experience and a forethought.
I am 6'4" and of slim-ish frame. That passage just sucks.
