Thank you all for the great info posted here. I'm going through some of the same issues and have found a lot of great info in these threads. We went from a 29BH with one slide to a 32 BHDS that is easily a foot taller and 1,000 lb heavier. Dealer set up the hitch and kid looked about 20. "Yep looks level". With the 29 I really barely knew it was back there. With the 32, it was white knuckle until I raised the Equalizer L bracket one notch. Now it's more stable but the nose of the TT sits up a little, which I think is why I now get a push from cars passing me while before it was just trucks and wind. I'm looking for a scale but in the meantime I'm going to measure everything per the instruction book and probably lower my ball one notch. EQ bars aren't perpendicular with trailer frame either. So, moral is as many have stated, get to know your hitch sooner rather than later and do it yourself.
Thanks to all who have posted previously.
