My sister has a Expedition for sale that has a 10,000 pound towing package, 5.4L engine and seating for 8. That way you could take all the grandkids and some of their parents to do the cleaning! To bad you live more than 2,000 miles away. ..
I think that any of the proposed trucks will work great with a 500 - 750 pound hitch weight and say 800 pounds of passengers. The 5+ liter engines will not need to slow below about 50 on the steepest of hills.
One thing about the super cabs, the kids will tend to grow taller, and will complain about being the only one in the back seat. . . .
You might be looking at much larger trailers with a slide out once you have the ability to safely tow something in the 27' range. My buddy was looking at new 26' Fleetwood, when they came across a 27' that had been traded in of the same floorplan and model, but one year older and 1 foot longer. So they bought it.
For a tow truck, he had a 351" F-150 with a lot of add on things to keep the engine cooler, and larger transmission cooler, ect. He traded that in on a new F-250 with the same 351" engine, but a much larger radiator, much larger brakes, ect. He was much happier towing with the new truck than the older one.
Good luck,
Fred.
