I can tell you that when I tow my 20' enclosed trailer loaded at 8000 lbs with my Ram 5500 I do not feel the trailer at all behind me. However, I do see slower acceleration and quicker downshifts on grades. Towing the same with my Ford F250 I could feel the trailer resisting change of direction I made with the truck. I have a little flat bed trailer loaded around 2000 lbs that I sometimes tow with a VW Jetta - I can feel the trailer behind it because it does not have trailer brakes, but I cannot feel or even see it behind my Ram 5500 unless I am making a really tight turn.
There are times that you get combinations that don't fight each other, but it is typically when the tow vehicle is heavier than the trailer (VW excluded on this one).
