We have a 2015 F-150 XLT 4wd extended cab, with max towing package. The sticker on the door says 1,930 pounds. Purchased a Sherline scale and the tongue on our 2003
Bigfoot 25B25RQ weighs about 825 pounds, not counting the Blue Ox hitch (75 pounds?). We carry around 150 pounds with two trikes and a few tools in the pickup bed, and perhaps 450 pounds (including Terry and I) in the cab.

In theory we have over 400 pounds to spare.
So far we average around 11 mpg pulling the
Bigfoot, but we're pulling a 6,300 pound, 8' 4" wide
fiberglass camper (total camper weighed separately, full LP tanks, 1/2 full fresh, partial grey and black tanks, and all our gear).
Our 2003 Honda Odyssey pulled our 2,800+ pound 16'
Scamp side bath, with trikes and other crap in the van, but only at 50 mph in mountains, and got 14-15 mpg. I felt it was at the max with the
Scamp and all the gear.
Our 2008 Honda Odyssey pulled our bare bones 17' side dinette
Casita (no bath, no fresh, black or grey tanks, no hot water heater, etc) that weighed around 2,300 pounds with ease, including mountains, and got 16-18 mpg. The 2003 Odyssey pulled the lighter
Casita, much easier than the heavier
Scamp. At one time we had both Odysseys, but
sold the 2008 to purchase the F-150.
When we first purchased the F-150 the 3.5 Ecoboost got 20-22 mpg not pulling. We're now nearing 30,000 miles and get 23-25 mpg not pulling.
Do the math and give yourself room to spare.
