I too would like some input regarding the "porpoising" or se-sawing sometimes going down the road.
Is a little acceptable or is it a sign that something is wrong.
I had not a good trip home from the dealership where I purchased my 19" hybrid. I purchased a weight distribution hitch and electric brake controller from them and had it installed by them. The hitch was not installed correctly the TV ball was 4-6 inches higher than the TT hitch so my camper had it's nose up in the air going home. On top of that, we were being chased by a bad rain storm that caught up to us as we got home.
Anyway we were doing some swaying (enough to feel that it was dangerous).
I changed the height of the hitch and it rides much better. But it still feels like I can feel some bouncing going on.
Any help or opinions?
