FWIW, a very good friend of mine pulls his 5th wheel (I'm guessing 9K to 10K, not a huge one) with a 2013(or 14) extended cab, short wheel base, 4x4 F250 w/6.7 PSD, bone stock. I do not know his gear ratio, size of fuel tank, or the speed at which he ordinarily tows. However, he claims 16 MPG towing in and around FL and GA. He is a VERY trustworthy person and has ZERO ego. I do not doubt for one second what he has told me.
Might be a trustworthy guy but he's sadly mistaken (or just really bad at math) if he really believes he's getting 16MPG towing a 10k lb 5er.
