You're probably going to be in the range of 13'-2" to 13'-4". A lot depends on your truck and your hitch setup as well. Hook to your truck and park on a level spot. Use a 4 foot level and get on your roof with a tape measure. Places the level on the front ac unit and level to one side of the fiver. Drop the tape to the ground and have your spouse hold the end to the ground and then simply measure to your 4 foot level while holding level to the unit. Do this and you will ALWAYS know your height at those gas station canopies!
