My land was flat also. After the foundation went it there was a slight rise to the concrete floor like in any construction. I even had a second door installed out the back so I could just pull in and pull right out thru the back.
They filled in landscaped and the concrete pad to the building looked flat as did the ribbon to it.
My door had plenty of clearance measured to my MH sitting on flat concrete in the front driveway. But its a math problem slightly raise the front end x amount x height somehow increases exponentially made mine a real looser for me.
And by god it was only an inch+ that prevented the ac unit from clearing the top of the door.
Here's the warm expensive heated home I planned for my RV that she NEVER was able to park in during the cold winters of the North.

We were limited in the height of ours by the fact we were scabbing on to the roof of my stick built/bricked shop that was already there so it would look like one building. To meet code we needed at least a 12/4 pitched roof so the best I could squeeze out was a 13 foot tall door. Our 12'6" high motorhome was no problem. When we changed to the Excel 3 years ago I checked and rechecked the height which was listed as 12'8". We ordered it with a bedroom air and when we got it home for the first time that a/c would not let it go inside. The dynamics of the concrete tilt was probably part of the reason, plus the height I had the hitch set, etc. Bottom line was I could not make it work. I did manage to revise the trim above the door and gained about an inch but that still was not enough.
I called Excel and they came up with the solution of putting a lower profile a/c in the bedroom. The one that came with it was a low profile Coleman at 11 1/4" but Coleman had just come out with a lower one at 8 1/4". All I had to pay was the difference between the cost of the 2 units as the taller one was just an a/c and the shorter one was a heat pump. I don't have a lot of room to spare but it fits.
Not sure if it would help you to see if there is a lower profile a/c.
