UPDATE: in case anyone cares...ended up taking the parts for the hitch with me, i figured that they would have filled the propane bottles and filled with water to make sure everything worked when picking up and that would just be adding more weight. well i was correct. so i went ahead and put the ball on the hitch assembly (that sucker was fun) at home so i could do the rest at CW. Well long story short they ended up asking me if they could install the hitch while we finished with paper work. (they knew i would be installing hitch myself afterwards) CW actually did a great job it looks like, but ill still be going over it myself later this week ;) but just wanted to say thanks for all the replies everyone offered

Went practicing backing this morning for like 2 hours...this equalizer hitch is noisy!! if i hadn't read about that i for sure would have thought dealership did something wrong...haha
