Stepped up our camping game with a 1966 Apache Buffalo Mesa tent trailer. Weighs about 785lbs and the Cruze towed it with no problems. We camped at Lake Almanor in California.
I went with the Curt hitch that I got from another member on Cruzetalk. Ended up with the Curt wiring harness because I did a bulk order from Amazon and got a decent deal on it.
No upgrades to the rear springs. With some gear loaded in the trailer the tongue weight came to about 82lbs. You could tell that the Cruze had a load in the back but had no problems even with some unexpected large bumps.
Also, the Cruze is crazy fun in manual mode on dirt/gravelish mountain roads. We were going to be late for my little ones horseback ride (due to some slow drivers on narrow paved roads) so I popped it into manual and went to town. 10 miles later and one slightly worried wife we made it..... a few minutes late. The last group was late getting back so technically made it on time.
