Afrnd2all,

The one specific number you left out of your post is the yellow door sticker on your truck. That payload number, if your truck is a Lariat, is probably about 2100 pounds. Given 500 pounds of passengers and cargo in the truck and a 150 pound fifth wheel hitch, that only leaves around 1450 pounds for your pin weight.

Using your trailer weight figure of 12140, at 15% pin weight you're on track with 1821, about 371 pounds over your truck GVW. If you consider that you could be closer to 25% pin weight, that would be 3035 pounds, or closer to 1585, more than double the remaining payload of your truck with passengers, cargo and hitch.

That trailer is much better suited to a F350 and will very likely be "over GVW" for any model F250 with a diesel engine.
