Last year we built a garage for our Kedron (16' XC3 compact with 17" wheels and cruise-master suspension).
We were advised to make the entrance height at least 3.2m, we made it 3.3m just to be sure. The van fits comfortably with a safe clearance. The highest point of the van appears to be the top of the Air conditioner, closely followed by the TV aerial.
Note: On measuring the Van max height it appears to be 3.1m, but measurement was done in a hurry and a bit roughly when we got the the van home, before putting it in the garage.
If you make it 3.3m you should be OK, I am not sure what other Kedron model van heights are?
Good Luck
