I thought 13' Compact Jr was 900 lbs to 1000 lbs and Casita
Patriot Deluxe 13' 1465 lbs. plus 190 lbs. tongue for 1655 lbs. total with w/bath/AC, total lightly packed maybe 2100 lbs. Casita
Have pulled for 5 years 1000 lbs with our old Echo sedan, actually car road better with trailer?
I think Towing is about: hp / gearing, suspension / hitch style (class, sway bar, WD) cooling systems, RV heavy duty Shift improver Kit and braking systems.
Sometimes we can change hp or gearing other times suspension upgrade or WD hitch then we can add cooling and braking even car RV heavy duty Shift improver Kit
this is a judgment and in the end we all decide.
We just have to make reasonable choices and keep it legal for our area
