From what I've read, you need the 2.4L engine, 4x4 drivetrain, and a factory tow package to get that 2000 pound rating. Assuming all that...
A tow rating of 2000 pounds allows you to tow most 13' molded trailers, but no larger. A fully loaded Scamp
deluxe front bath model with all the bells and whistles will push your limit. You will want a unit with brakes
(not all have them) and 7-pin wiring with a brake controller on your vehicle.
If it were me, I'd stick with a more basic 13'er and keep the loaded weight
well under 2000 pounds. The frontal area of a Scamp
or similar, while fairly aerodynamic, is a lot more than the 20 sq. ft. used for tow testing in this weight
class. If you can find a Hunter Compact Jr. or Trailswest Campster
, which are both narrower and lower than a Scamp
thanks to a pop-top design, even better.
