Winery Trailer, printed logo and cut vinyl lettering

I have someone who is wanting a 31'enclosed trailer done so I'd like to ask you a few questions if you don't mind. How tall and what is the font you used, I like how ou were able to use up most of the side of the trailer?

Arlon posted a good video on installing graphics on corrugated trucks and trailers. I realize the trailer shown isn't corrugated but it still has the rivets that need to be done.
