Well we didn't buy the Zinger, instead we got a '14 Jayco 267BHS. The trailer is 29'11" and has a GVWR of 7500 so hitch weight of about 975 @ 13%. I had the dealer load all three water tanks to simulate a full load when we picked it up. The hitch I bought is the 1000# E2. Of course it was raining and windy when I picked it up, so there was a bit of movement passing semi trailers on the highway. The only time I was concerned was going down a steep hill that also turned, the trailer did sway a bit as I went started down. I'm not sure if it was the strong winds or if having the black and grey tanks loaded which added to much rear weight or a combo of both caused this. The dealer installed the hitch.
