Greetings All - we sold our Sandpiper fifth wheel and 3500 Sierra Dually. Kids are too big for the crew cab and the family is more comfortable overall in our 2016 Yukon XL Denali 6.2 with max tow rating of 7900 pounds. The travel trailer we are considering is 38? long with a dry weight of 7300 lbs. We are at the limit once lightly loaded and are wondering when length comes into play. Salesman swears - shocker!! - that with the Blue Ox hitch he sells, weight will be distributed and sway won?t be an issue. I?d love to hear from anyone with experience towing a similar set up. Many thanks!!
