An overload spring, say from Hellwig only slightly changes the static height, but it engages more with load. I run a set all the time, and it gives that level ride at max load, which no one should really expect without some accessories anyhow.

To clarify I was having issues with a ton of sway on the way to campsite. On the way home (picture of MPG) it was calm with no wind. I refueled each way.

I bought a truck not a minivan! If I load it to the specs I expect that I will still have good steering and visibility. In my opinion when you are nose up and sagged back you lose steering and also visibility. I get it if you make the poor decision to overload your truck but that wasn't the case here.

I agree with an earlier post that these trucks are turning into grocery getters. Just overall this F150 seems like it is a step down from my 2012 and I hate saying that because my wife tried to convince me to keep the 12.

Yes if I was pulling a camper full time I would get a 250... But a truck, any TRUCK should be able to pull without a ton of sag!

Heck I had a distribution hitch and I literally had it has supportive as I could!

I agree with this statement 110%.

In comparing to my 2004 screw 5.5 my 2015 6.5 with factory LT tires handles my trailers much better, my big test will be moose hunting in a few weeks with a modified rv/toy hauler with 3atvs and gear. Should be around 7000lbs altogether. I have noticed steering is slightly touchy(load or no load) but got used it quickly. I have pulled a 5000lbs boat with my fathers 2013 same config as my 2015 and it hauled very well. I dont think the 2015 is a step down, more like a different way of handling that you have to get used to. Sort of like going from a ford to say a dodge, the feeling is diffrent and at first it can either be better or worse but overtime it becomes your new normal.

I sold my 2011 F-350 6.7L diesel for my 2015 F-150 3.5EB. I used to tow a lot more, hardly ever tow much anymore.

I love my new truck, but yeah...if I was towing a lot it would be another F-350 diesel. For pure towing the F-150 just doesn't hold a candle. I remember pulling an 8000lb trailer up the rockies on I-70 out of Denver and it never shifted out of 6th and held 70mph all day long. Only time it would down shift is if I needed to pass. It truely felt like hardly anything was behind me.

However, for a daily driver the F-350 was just not much fun.

I can't feel much difference in ride and stability from my 09 to my 15 towing about the same load!

This seems a bit melodramatic to me. In the OP your picture doesn't show a ton of sag. To me, it looks almost perfectly level and you are nearly maxing out the payload.

I can't comment directly to how a 2015 F-150 compares to a 2014 F-150 or prior. However, judging from what I've seen the 2015 F-150 isn't just a grocery getter.

TFLTruck rates the 2.7L as they top choice for towing in the class. I have a hard time believing that the 2.7L beats out everything else in the class when towing 7500LBS but it at least shows the truck isn't just a grocery getter.

I personally wouldn't feel comfortable towing nearly 10K with a 1/2 ton no matter what the specs say. Only way I would feel even close to comfortable is if I had the HD payload package and had 18 rims with LT tires.

TFLTRUCK rates the 2.7L as the top choice for towing in the class? Now that is really a stretch! A small displacement 6 cylinder gas engine with turbo chargers, the top choice for towing, really? Maybe the weekend warriors will buy that, but it's just more marketing to me.

Like I said I don't buy that either. They were basing it on 7000lbs loads not max load for the class. They reasoned that it was the best driving with that kind of load.
My point was that saying an F-150 is only a grocery getter seems like an exaggeration.
