Using modern passenger vehicles designed for daycare centers, grocery stores and comutting are not ideal tow vehicles.
Users claiming they are often boast ideal conditions but are grossly exceeding hitch ratings, payload, or gross combined weight ratios.
Passengers, coolers, clothes, drinks, firewood, water, fishing poles, chairs, generator, tools, gray/black water, and bedding are examples of everyday camping trips. Some days more goods such as bikes, canoe, quads, and grills. All deduct tow rating of truck or camper CCC
Loading up the trailer adds tongue weight. Exceeding tongue weight limit can cause crash to occur and harm others
So use that 3500lb rating all you want, destroy the drivetrain and stay out of the ditch!
My trailer is within all limits, and that's not all that hard with this trailer. It was harder with the previous one. I use a tongue scale and weigh the full setup periodically at a Cat scale. My TV has been towing this trailer and the one before it (which was heavier and had a slightly larger frontal area) since 2008. It now has over 100K miles on it, some 60K of that towing (all over the East, including mountains in WV, MD, NC, KY, TN). I've had no issues, and had to make no repairs, to the drivetrain. I follow the hard-use service schedule. The tranny still shifts the same as it did when new, and the engine still runs as beautifully as it did when new.
Towing, it's very stable - low center of gravity, long wheelbase. (It helps to have a good hitch too.) The only modification made was to add Timbrens to the rear suspension to help prevent porpoising. I don't put any cargo into the minivan - just people. That keeps the weight within limits. (It helps that all of the people are lightweight. I'm the heaviest at 150 lbs.)
Sorry - my experience, and that of many others who have actually towed with Toyota and recent-model Honda minivans, disagrees with what you say.
