20 foot tandem bumper pull with up to an 8,000 pound tractor
Also, in the market for a 16 foot bumper pull stock trailer.
Drive 30-35,000 miles per year with about 10 percent or slightly more towing.
I pull a 20ft bumper pull with approximately 7000# tractor for a total of a little over 10,000# with a 6.8l V10 Super Duty and it will pull it OK but I only pull it once or twice a year for less than a few hundred miles. If I pulled 3000 to 3500 miles per year as you suggest I think I would be looking for a diesel, although Ford has a new 7.3l V8 with a lot of low end grunt that may be worth a look. The diesel will also give you some compression braking which would be important to me if I towed in the mountains much.
Those of us who haul heavy stuff, like a tractor to the dealer to get worked on get by with a gaser just fine and the are much better to live with daily but 3500 miles towing is a lot of miles.
