15,000?76" tall, 4wd, 700 ft pounds, turbo intercooled. 6700 pounds empty. Check! 15000 towing capacity, check!
If you go with dual rear wheels, you kin tow considerably more.
But I don't tow routinely and max payload I've done in my F-150 was 2300 lbs of crushed stone for ten miles, just a bit overloaded, yes.
So if you need higher load capacity, then no choice but a HD model ..
