I see Eric H chose to put his air dryer boom on the wall like us except our center boom has 2 hoses. We already have 2 hoses ... main wash hose & foam brush hose centered with a Z-Boom. Someone told us it would be better to have 3 booms in the center. Has anyone done that? If so ... did they regret it? I am thinking that the booms-hoses will get criss-crossed occasionally either way. Customers have creative ways of accomplishing that ... much to our chagrin! We used the Mosmatic-Hydrospray air boom which I believe is longer in length though.
