Hi Royboy
I have assumed that the BT where stored is some distance away from where you are, otherwise you could take a step ladder and tape measure and check it yourself.
You may need to consider more than just the physical height of the BT and the location of the air-con.
Is the approach to the doorway flat and level?
If there is a bit of a ramp and the air-con is more rearward than centrally placed, then the BT would have its rear end poking up higher until the tug and the BT were both on the same horizontal plane. A drawing to exact scale might help you here.
We have a 19 ft with the air-con centrally placed.
We positioned our boat upside down on top of a high canopy on the tug, purposely, so that the keel of the boat would be slightly but minimally higher than the air-con as an early warning device, for low limbs and lower than usual servo awnings that don't have the height posted.(See our signature pic on this post.)
The keel of our boat is at 3.05 m above flat ground.
Yours may be different depending on the type of air-con. Some are higher than others. You might also have to consider a Sat Dish height in your deliberations.
A phone call to the BT factory might help you here also, you might need the details from your VIN plate to help ID the van build.
More height is good if you can afford it, as it helps to reduce the roof temp of the BT, insulation under the Iron roof helps also.
Roller doors are fairly bulky above the opening and electronic tilt doors have a control box the location of which needs consideration.
Our carport where the BT is normally parked has the sides at 4 m with the roof lined and centrally peaked and no doors.
Hope the above helps.
Cheers

Hi

20ft BT with Aircommand is 150mm higher @ 3.2m from memory. However, I would not go under a bridge displaying less than 3.4 in height, plus would make sure that approach and departure angles are ok.

'Hope this helps.

3.5 metres will give you some wriggle room.

From memory, I think we're about 3.05m. We operate on the 3.4m - 3.5m clearance factor.

Have a 75mm additional ceiling height with our 20' BT and because we have just fitted an AirCommand Cormorant, I pulled the shed roller door onto the top of the a/c when we got it home.

At a pinch 3.3m is clearance, but look twice at 3.4m obviously. If the road has been re-sheeted recently, 3.5m gives safety

My van is 3.2 so what I have done is to use one of the long uhf arials from ARB which on my car gives me 200mm of clearance so if the arial clears I am okay

.............and don't forget about the tree limbs, they have no height sign and they can come out and strike you at any time.
