I have a 17B on order and I'm wondering about the actual width. It is listed at 6' 8", but is that the measurement of the box or the actual width taking lights, awning supports, grab handles, etc. into account? The reason I'm asking is that the gate opening to my driveway is 7' exactly and I need to know if I need to widen it to accommodate the new member of the family. I'm using an electric tug with my current tent trailer and can "thread the needle" quite well with an inch to spare on each side.
