I towed my #6500 TT with a 2011 3.55 5.0 4x4 SCAB F150 regular tow pckg. note* I bought the truck before the TT not knowing the true dynamics of tow capacity and payload. 5.0 payload isn't good without the max payload option. I was within 100-200#'s of my GVWR with passengers/cargo/TT tongue weight.

Upgraded the truck after driving in the Adirondack/finger lake region. Need over 4k rpms to get to the meat of the torque to get up long grade changes and even had to romp on it to get up to highway speed. Once you were cruising it was okay, it would gear hunt even with 6th locked out but expected with high revving V8. You knew the trailer was in tow with the 5.0, or even hauling a load (pavers, topsoil, etc.) It got the job done though. Couple that with the 147" wheelbase and I was ready to upgrade.

The 5.0 drivetrain will get the job done but doesn't really feel comfortable towing/hauling at its towing/payload limits, YMMV.

Sounds like you had bad fuel, clogged air filter, dirty fuel injectors or defective wire by throttle accelerator. :)

Drove in 40 mph winds and very large hills with demanding grades, always had reserve power and never needed to have 4K rpms to maintain speed. Trailer is a 6500 lbs loaded tall Jay Flight 29' length 26BH.

Never a problem controlling the trailer going down hills or even in wind with my Reese Strait-Line hitch. Truck has plenty of engine braking and torque down low. Has more torque down low than my previous, nearly identically configured 2010 Screw 4WD 5.4L w/3.55 LS truck. Same transmission gearing but slightly lower ratio axle gearing that would had supposedly equaled the torque between the 2. BUT the 5.0L still had gobs more torque down low, than the 5.4L, despite that.

Perhaps you're just use to driving 3/4 - 1 ton diesels that rarely rev past 3000 rpms and make their torque peak at a barely moving 1500 rpms.

I've towed with numerous 1/2 tons and midsize trucks and this F150 5.0L is the best by far, out of any of them.

Throw some LT tires on the truck and you'll get a stiffer side wall that hampers the back and forth wallowing motion that P-rated tires are known for. That can be un-nerving for some.
