My opinion, but you don't need a 10k plus trailering rating in order to pull a 6800lbs trailer. Let's say your trailer is 8k lbs loaded, I have a Trail Boss and it has a 9500lbs tow rating, I would feel more than comfortable towing 8k lbs. I have a travel trailer that weights 5800 lbs dry, I estimate that it is around 6500 lbs when we travel. I haven't towed it with my truck yet but I have towed it plenty of times with my wife's Tahoe, which has the max trailering package and a towing capacity of 8600 lbs, the Tahoe handles it just fine. We took it into the mountains last summer and I had no problem maintaining the speed limit going up the mountains on the interstate and none of the temps ever left the normal range. I have no doubt that my Trail Boss will handle it without issue.
