Congratulations on the new JaySport and welcome to the forum.
Jayco Customer Service might be able to help. Give them a call with your VIN# in hand and ask them. You might be able to ask your salesperson if it's a matter of measuring another trailer on their lot.
I don't understand your tow vehicle's weight limit (2000lbs without WD hitch) and your trailer's weight (2700lbs gross weight from Jayco's site). Does your owner's manual say it's OK to use a WD hitch?
