The brochure for the year 1999-2000 Burro models lists the following:
17' has a dry weight of 1900lbs, 125lbs tongue weight.
(Mine has an on-the-road weight close to 3100lbs and a tongue weight of about 275 lbs).
14' has a listed weight of 1100lbs, 100lbs tongue weight.
In the tradition of such brochures, the weights are without any
options at all (judging from the disparities probably not even air in the tires).
them on a real-live scale is the ONLY way to tell.
