the equalizer is great....a little loud, but don;t worry about that...it sounds like something is wrong, but that just means it's working...I posted about it at RV.net and learned about the noise........I am at the upper range as well, and just installed the airbags 2 days ago....probably try her out this weekend for a short trip!.........bottom line is the equalizer is a very easy set up and hook up.....no groaning and manipulating...put it in the hitch, push it over, lock in the L clasp...voila!!
