We have a '10 F-150 w/ Max Tow Package and a Sundance 285BH. The tow package puts the tow rating at 11,300 and GCVWR of ~17k. We recently pulled some 4k miles on a vacation starting in Montana thru Wyoming, S. Dakota over to the Great Lakes and back. Most of the time, I didn't notice the trailer was even there ride wise as it didnt squat the truck more than an inch. I did have to trade off some RPM to maintain speed on some hills and just had to give up some speed on the worst hills, but for the most part I am very happy with the combination.
The area we need to watch is pin weight as the RAWR is the limiting force. For that trip, our first out of town, we emptied the 5er pretty good. I am going to go to the local CAT scale to get a full set of axle weights done with full camping load, not a minimized to see where we are at.
If we were going to be pulling full time, there is no way I would have gone with such a small truck, but I dont see us goin gout more than 1/2 dozen times per year right now so I wanted a truck I would be happy with the other 11 months of the year.
That being said, I have ready many people say that it can't be done, it shouldnt be done, etc. But if you are defensive and cautious and stay within your abilities as a driver it is a suitable weekender combination.
