I pulled my Big Bend 16' trailer yesterday. I think the trailer is something like 5,000 empty. Pulled it 80 miles empty. Loaded it up with my 20-year hoard of ammunition and gun stuff and pulled it 120 miles back home. I'm sure by how sore my back is today that I was running over 10,000 loaded. I had it stacked full of mainly ammo to the gate in the middle of the trailer with much of that being shotgun ammo. Averaged 13.5 MPG. My Tundra usually got 15 MPG on the same trip empty. These new F250s are pretty amazing trucks and really pulling machines. Really barely noticed the trailer back there and it accelerates about like diesels of 25 years ago did empty but with a load. Hopefully, it will be reliable.
