A few years ago I took the boat, motor and trailer to the local feed store and had the whole package weighed on the "drive-on" scale...the bm&t weighed in at 3150 lbs., trailer attached to the tow vehicle. My question is, there is a tongue weight, and I honestly don't know what that might be, probably around 300lbs, maybe less...my question is, should the tongue weight be added to the 3150lbs?
