Thanks for asking. I guess I needed to update this anyhow. We tow Pete, our Flying Cloud 27 fb twin as previously mentioned, and I also have a 21' bay boat (maybe 3800 lbs) and a 7x16 enclosed cargo trailer (2100 lbs empty, maybe 4600 loaded with an antique tractor) and I can truly say that the new truck tows them all very well.
I was talking about this the other day with a local friend of mine and he asked "why does it tow better than the '13 you had?" Well.........I think it's a combination of things. Drivetrain, wheelbase, frame strength, tires, and maybe a couple more. This is gonna get wordy, but here goes.
The 3.5L Egoboost (yes, I know I'm being silly calling it that) is truly awesome. I liked the '13 5.0 (a 2wd crew 145" WB, same 3.55 gears), but it always felt strained towing Pete. I could never leave it in 6th gear, even with Tow/Haul on, it just downshifted all the time. The EB allows me to tow in 6th a lot of the time, and it hardly ever downshifts on our Florida grades
. I know that's funny, but we really do have some decent 6%ish short pulls around the middle of the state, especially on the turnpike that will test a rig. The EB drivetrain makes big torque at such lower RPMs than the 5.0L did, that it just pulls. Pretty loaded rig as I said in first post, and I usually drop to 5th gear manually ahead of those grades, but seriously, it just pulls. It never goes into 4th and I get a big smile on my face! Oh, and accelerating up to speed from a stop is more like running empty than the 5.0 ever was.
The frame on the '15 F150 is much stiffer. The bed hardly moves going across creek beds or into parking lots (yes, I use my truck in the woods), and that means it is a more rigid chassis. When I load the ProPride jacks to balance the rig, I'm convinced the hitch and chassis on the '13 flexed a bit. The '15 doesn't, and the hitch is stronger too as a bonus with the MaxTow package (seems like it is bolted to the bumper?), so it really doesn't flex. My truck history includes a 2003 GMC 2500HD DMax with the infamous twisting tube hitch that I replaced, so I know about torque twist when loading W/D onto a truck.
Tires and wheelbase length also come into play for more rigid towing, and I feel that both the tires and the longer 157" wheelbase on our particular '15 make it more rigid while towing Pete. We are blessed to have scored a deal on a used ProPride hitch, and while it seriously improved the towing with the '13, it literally feels like Pete is welded to the frame of the '15. You especially feel the rigid combo when a box truck passes on the Interstate and there is no "hang on to the wheel the bow wave cometh" any longer. As to the tires, on the '15 they are "XL-rated" Goodyear Wrangler Fortitude 275/65R/18 that carry 2756 lbs @51 max PSI. I run them @ 46 PSI and they ride well loaded or not, and are much stiffer than the really soft Michelin's on the '13 2wd. Those tires only held 44 PSI max and it seems like carried under 2000 lbs max. I would have soon replaced those with at least D rated LTs had we kept the '13.
Living with the '15 has proven itself well. It only has like 2400 miles so far, but I drive it nearly every day (I'm blessed with a 5 minute commute to work). It is so much more comfortable to me than the '13, that I'd rather drive it than my wife's MKX. Yes, it's an XLT, so no leather, but the seats on the Sport are the same 10 way buckets (heated, but not cooled) and center console from the Lariat/KR models. I can't prove it, and haven't researched it, but i think the crew cab is even bigger on the '15 too, the rear doors certainly look bigger next to my son's '14.
So there you have it, our new '15 F150 is meeting our needs very well. Ford really knocked it out of the park with the new model (F250 is next H/D fans
). But really, all the new trucks are SO much better than those they have replaced in recent years from ALL manufacturers. I happen to be Ford guy, probably always will be, but these new trucks are really great no matter what badge you buy. How else would they keep getting us to spend money?
Hope this is helpful to someone. As I said earlier, it's just a truck, a tool, and I don't mean to be bragging. But it's proving to be a very useful tool so far for what we use it for...........
