Any reason I'd need weight distribution?

WD hitches were very much needed back in the days when Grandpa hooked up his 1960 Buick to an Airstream. I think a lot of folks just assumed that was the way to go. Modern pickups are a different story. The manufacturers are taking a new look at that old mentality. GM makes a WD hitch optional for their pickups in many cases now. I use one for what I perceive to be a better ride. Might not be, but I already owned one.

Tom,
There is likely some truth in what you say. However, one needs to read carefully what and "how" the truck manufacturer writes these recommendations. For instance, my Nissan owners manual states I can pull up to 5000 pounds without WD, and up to 6300 with WD. It does not however directly state tongue weights in those limits. So for instance, if we take their 5000 pound trailer limit with a typical boat trailer tongue loading of just 8%, we would have just 400 pounds on the tongue. A 5000 pound camper trailer with 13% tongue would be 650 pounds.
I might consider this truck to be "ok" with just 400 pounds of tongue on just the ball. I would not however consider it a good setup with 650 pounds.
Just something else for the OP to consider and research. Bottom line is the RV companies and the vehicle manufacturers tend to let the marketing departments play somewhat fast and loose with the numbers games.
