Do you know what the part number is for the rear double valve kit for the BX ($350). Asked my dealer, and was told that none was offered. Won't be the first time that the customers know more about what is available than the salesman.Scratching my head about the 3rd function location... When you get a grapple you are going to have like 10 feet of hose. I would move the 3rd function back to the front right foot position. The rear double valve kit for the BX is a steal, have them install that kit when they move the valve. Its like $350. You will get all kinds of use out of it.
