We pulled our new 13' Scamp
over 6000 miles so far this summer. Mountains, flat land, almost off roading. All this with a Suzuki Gran Vitara 6 cyl. It is the same as the Chevy Tracker. We even took it up to Canada to visit the plant, where they are both made. It pulls wonderfully! We load carefully. Have no electric brakes
. No sway bar. No problems, so far. Good Luck!
