All I can do is relate my experience with (4) 1/2T pickups pulling rv trailers dating back to 1978, 3 trucks ended up with over 100K on them when I got rid of them and still had the original rotors &/or drums on them. My present 05 has over 93k on it and has had new pads and resurfaced the rotors @ 80K. This truck has towed (according to the wt police overloaded & unsafe) for at least 75K and I don't see how a 3/4T could stop any better than I can either towing or not. With ABS brakes, it is just about impossible to lock up all 4 wheels at one time.

Not wanting to start a discussion, just stating my experiences.

I tow that very fifth wheel (8285IKWS) with a Ram 1500 Hemi and it pulls like a charm. I just came back from a trip through the mountains and had 0 issues with pulling power, stopping power, sway, etc. I also put the air bags in the rear coil springs (otherwise it will look like your brights on are on all the time) and put 20lbs. in while pulling. The Rockwood Signature Ultralight series is truly a half ton towable series, unlike most others that advertise that way.

What the Pastor and Old Coot said. Both speak the truth and gospel about Rockwood Signature Ultralite/ Flaggstaff Classic.

The OP is close to GVWR on the trucks capacity. I would add a extra tranny cooler. Also load light if possible. The Ratio of what he is proposing to tow with 9,500 and my 11,200 he still should be fine.

I personally prefer a heavier truck, but have not heard anyone complaining about their Eco-Boost. However, I'd like to hear from someone who tows on steep grades at elevations in the 8000' to 10,000' range (Rockies). The twin turbo chargers should be helpful there, but long, hard climbs at those elevations will test any rig. Before I bought a 2500 series diesel, I was towing my Rockwood 5th wheel with a 5.7 liter half ton. It did a pretty good job, even in mountains, but I began to wonder if the drive train could hold up towing in those conditions year after year.

No wonder you call yourself OldCoot. Pretty hard not to start a "discussion" after those remarks. But I won't say anything except this: seems to me that wheel lock should be impossible with ABS?

Road Test Review: 2011 Ford F-150 FX2 3.5-liter EcoBoost V-6, Part 2 - PickupTrucks.com News

On I-70 in Colorado, on the same route we did our Rumble in the Rockies, we also ran the F-150 pulling the 9,000-pound trailer. We were stunned by how well it pulled at such high elevation on the 7 percent grade to the Eisenhower Tunnel. It was so strong that we had to start testing at 10,000 feet to ensure the rig didnít climb the hill at an unsafe speed at wide open throttle. The EcoBoost F-150 ran the quarter-mile in 27.83 seconds at 50.83 mph Ė more than enough to keep up with or pass traffic. Thatís a performance we donít think could be easily matched by a non-turbo gas engine, even a large-displacement V-8.

Now, compare that time to how the truck-and-trailer pair performed on Davis Damís shallower 5 percent grade at only 2,000 feet of elevation, where itís easier to gulp oxygen to feed the engine. Here, it ran the quarter-mile in 24.56 seconds at 58.47 mph Ė not much slower than it did in the Rockies.

F150 Ecoboost towing Rockwood

OK,

When I heard of people pulling heavy trailers with a V6 it raised my eyebrows......

Then I started doing a little research and discovered the results of the eco boost were real. The eco boost will pull especially in the mountains. One tester commented that turbos will trump horsepower every time in the mountains. This is not the original pull test that I found but the results were the same. And of course it is presented from the perspective of the eco boost being a pulling beast and it is.

http://youtu.be/-n2uEx8CojE

But, is it really worth it to go with a V6? Here is another article written from the other perspective trying to sell another brand and engine. I have a 5.7 Tundra and that is how I found this article. This article deals with durability and longevity of the eco boost. Is it accurate. It seems to be.

http://www.tundraheadquarters.com/bl...lacement-cost/

So,

What would I do if I had a eco boost and wanted to pull a heavy RV with it? I would hook up to it and pull it. And, what would I do if I had a 5.7 Tundra and wanted to pull the same RV. I would hook up to it and pull it as I have done. Would I personally prefer a 3/4 ton for my trailer? Of course but my Tundra pulls and stops it fine and I do not want to spend the money on another truck.

Please, please do not attack me. Just presenting the facts as I see them.......

Ken

There is no ABS on the trailer. I have locked it up on wet roads, With my Integrated Ford Brake controller it does take into account sway and truck lock up and feathers the trailer brakes to match.

Dating back to 1975 a 24 ft Citation TT, the breakaway switch pulled due to your truly not running the lead correctly, The trailer dead in the middle of a turn at 25 mph locked up and stalled the 454 Suburban dead in its tracks. The trailer should stop the load, no question.
