Remove aerial. Lower pressure in tyres. Say you don't know the height. Ask them to measure it.I hope it didn't go through the roof.
I had my motorhome serviced recently and asked the garage if they could do the MOT at the same time.
They said they could, as long as my 'van wasn't over 9 feet tall.
I checked the manual which stated it was 9 feet 1 inch!
As that didn't include the TV aerial, I decided to take it elsewhere.
