The first consideration in pole barn height is the height of the door. In order to have standard radius curves on the overhead door rails, we went with 14 foot barn sidewalls and 12 foot high door. We can fit our class C Motorhome just fine, but most class As will not. We knew we would not likely ever buy an RV taller than 12’.
You didn’t mention if you intend to have an interior ceiling or open trusses. If the inside is all open framing, like ours, there is plenty of room inside to stand up above the 14’ wall height.
In 20 years of storing the RVs in a pole barn, I’ve never needed to service the A/C, so it would certainly not be a consideration for me in designing the building. I did recoat the roof and replace the vents on our old RV, and there was ample room to work on top of an 11’ high motorhome in a 14’ sidewall building, because there was no finished ceiling in the barn.
Lastly, you could maybe just do your RV roof work outside, for no more often than it should be needed.
