Thanks again for all of the good info. I think my approach for now as I learn more about this is going to be to control it with speed and routing.
I'm driving a brand new TV, and it's a new TT. The TV handles the TT well except for these stretches of road. I think I will just avoid most of it and slow down for the unavoidable.
I checked out my Equalizer hitch yesterday. Without listing all of the measurements the differences for the front of the TV seemed minimal to me (the uneducated). When I dropped the trailer on with no WD the front fender went up by 1/2". Adding the WD bars dropped it back 1/4".
The rear fenders dropped about two inches with no WD and came up about 1/2" from there with the WD bars.
I added a washer to the hitch to tilt the ball back slightly, and see no changes in the measurements.
So, the front is sitting about the same height, and the back drops about 1 1/2". Does that sound reasonable?
We're taking another trip in a couple of weeks, and this one will take us by a place with scales. So, I'll get loaded measurements of the weight while we're out.
