So we purchased our TT, it is a 2011 keystone summerland. 5680 dry weight. We weighed the yukon xl and it was 5900 lbs loaded. We estimeated the tounge weight someone between 700-900 lbs (between 6680 and 7600 lbs loaded at 10-12%) and somewhere around 150-200 lbs for the wtd and sway bar putting me right at my GVW of 7000lbs. It is a 2670BH and has like a 3-31/2 foot slide. We love it and got a great deal on it.
The only thing we need to find now is a antisway bar, we have a wdh, I have to figure out if were going with the reese dual cam or equilizer bar. Money is not really a factor but my wife would like to tow it by herself.
