I suspect that the unloaded weight of a
Burro may come in a little lighter than a similarly equipped Scamp. But it really comes down to what optional equipment is installed and what you carry with you. Figure 1200-1400# for an empty 13' trailer with cooktop,
fridge,
battery, LP tank, and not much else. Figure 300-400# for your stuff. Most people don't tow with a full water tank- it's on the wrong side of the
axle.
It's not hard to keep either trailer under 2000# loaded. Whether that will give a satisfactory towing experience depends on a lot of things. Tow ratings assume a driver and not much else in the vehicle. Ratings also assume a low-profile cargo trailer. If you carry extra people, pets or gear in the vehicle, if you tow regularly in demanding conditions (mountains, high elevation, hot weather, headwinds)- you may find your vehicle marginal or unsatisfactory.
Performance expectations also come into play, and they are highly subjective. Are you willing to gear down and blend in with trucks as you climb a grade, or do you expect to keep up 55-60 mph? If loaded semis are passing you, that's a good sign that you need more tow vehicle...
With four people, bicycles, and lots of mountains, canyons, and windy conditions, we find a 3500# rated mid-sized crossover a bare minimum to tow our basic 13' Scamp.
Electric trailer
brakes are essential, and not all 13'ers have them. In some cases, a whole new
axle is required to add
brakes.
