Just keep in mind, every foot of length is 8 square feet of sail. My 28' trailer is 224 square feet of sail. That 37' trailer is 296 square feet of sail. The wind force of 20 MPH against the 28' trailer is 458.752 psf, where the force against the 37' trailer is 606.208 psf. Thats an additional 147.456 psf being applied to the trucks pivot point.

The HDPP truck is meant to HAUL, not TOW. Read the fine print in the towing guide. Your truck does not weigh much more than mine does, and mass up front is what is needed to counter that big sail. I am saying this in the hopes that others don't take your post to mean it is safe to tow a monster trailer with a half ton truck, because it's not. You may feel safe, but in reality, that is way too much trailer for a half ton, regardless of what springs it has, or what hitch it has. It's not just wind, but leverage. If some moron comes along and taps the rear quarter of that trailer, you are done for. It's as simple as that.

Personally I would not go over 30' in length with a half ton, no matter how it is set up.

I think if some moron comes by and taps the rear quarter of a minivan, it's going to fishtail. Half the vehicles on the road are trucks/SUV, and if another truck/SUV taps the rear quarter of half the vehicles on the road, that vehicle is likely to fishtail.

I posted my comments so others can decide for themselves. When I was searching for a TV for my TT, comments and perspectives such as yours were the exact ones that convinced me to listen to other HDPP towing heavy, and to read Ford's specs.

That "for a half ton" perspectives of all the doom and gloom based on some unknown year truck with an unknown payload rating, and unknown trailer size were absolutely useless information.

I drive an tow a long and heavy trailer with a HDPP truck, and unless your experiences with towing your long trailer with your current model HDPP truck contradict mines, mines has more credibility than your doom and gloom speculations...your speculations doesn't trump my real world experiences.

I think you are supposed to be asking me about my setup, and not try to give me bias advice about my truck and what I can and cannot tow...I'd gladly honestly answer any questions you may have.

My opinion and advice is, I don't think YOU should tow over 30 feet, but I can.

It's not opinion, its fact. The HDPP is not for towing its for hauling.
Max towing on 2018 F-150 XL SuperCrew®,6.5' box, 3.5L EcoBoost engine, 4x2 and Max Trailer Tow Package. Not shown.

Max payload on 2018 F-150 XL RegularCab, 8' box, 5.0L engine, 4x2, Heavy-Duty Payload Package and 18" heavy-duty wheels. Not shown. Class is full-sizepickups under 8,500-lb. GVWR based on Ford segmentation

Maybe YOU are comfortable hauling around a huge sail in a light duty pickup, but to tell others, SURE, Go ahead and pull one, is just wrong. It's Physics man, get with it! You have a truck that weighs in at 6000 pounds or so, hauling a large wind sail that weighs close to 10K pounds. That is a trailer for a Medium Duty truck, not a Light Duty. There is roughly a 2000 pound difference between a half ton and 3/4-1 ton truck. That mass helps counter the effects of a long trailer, especially a bumper pull.

Not sure I follow. How is the ability to add weight a detriment to towing. A non HDPP would be out of the game for the 5th wheel I am considering. The HDPP leaves a couple hundred pounds on the table.

What is the unit psf? Pound force per square ft? If so, you have a unit error. I agree total wind forces are larger with a larger trailer, but not pounds per square foot. I really think you are off base saying the HDPP is less capable for towing, if you stay within prescribed envelope. The total trailer weight is allowed to be higher, but actually can not be due to pin/hitch weight, which will be the limiting number.

I know a 5th tows better, the 28' trailer is quite a bit cheaper however.
But without a HDPP, this would not be possible.
Only barely possible with the HDPP. Pin weight empty is 1500, (Includes batteries and propane) loaded I am guessing 1900 or so, 2000 with the hitch. Meh, right at the limit with me and my wife on board.

Maybe YOU are comfortable hauling around a huge sail in a light duty pickup, but to tell others, SURE, Go ahead and pull one, is just wrong. It's Physics man, get with it! You have a truck that weighs in at 6000 pounds or so, hauling a large wind sail that weighs close to 10K pounds. That is a trailer for a Medium Duty truck, not a Light Duty. There is roughly a 2000 pound difference between a half ton and 3/4-1 ton truck. That mass helps counter the effects of a long trailer, especially a bumper pull.
The HDPP with the 3.5 E.B.requires both the HDPP and the Max Trailer Tow Package, along with specific added features that makes this truck a great towing machine.

As for hauling, I don't care if the truck can haul 50,000 lbs in the bed, I'm not lifting all that weight in that high truck bed, and I still utilizes my Accord and my 6x8 utility trailer if hauling heavy...easier to load and maneuver.

This truck allows for the added benefit of having that quickness of a greyhound when not towing, but the stoutness above the payload and travel trailer towing ratings and stability beyond the regular F-150.

I'm not a truck guy, never had one, never wanted one, and still don't care driving this big, bulky and wide vehicle unless I'm towing. I rather drive my car over my truck any day, but at least I can get limited use out of it, but there is no way I would want an even larger, slower and more bulky truck than my truck, unless I absolutely had no other options with towing my trailer.

Enter the HDPP... the least compromise in a truck out there for me and no regrets.

An XLT 3/4 ton HD gas does weight approximately 2,000 lbs more, but it also has more that 2,000 lbs more towing ratings, and I bet you wouldn't advice that a 3/4 ton not tow a 12,000 lbs trailer.

A 1 ton dually diesel weigh approximately 4,000 lbs more than my truck, but can have 22,000 lbs travel trailer, and 30,000 5th wheel ratings.

That's only 4,000 lbs more weight, but well over twice the weight in trailer on the bumper,.and three times the weight in 5th wheel.

Continuing that logic, a Semi hauling an 80k trailer is a God Blessed Miracle!
There is still a limit for saail area for an F150 though, the reason for my original post. I’ll bet it is around 32’ of trailer (with a Hensley or Propride) before compromising safety.

As it pertains to towing in high wind, the weight of the truck shows up in over 30 mph windy conditions. If anyone doesn't mind towing on those windy days with those semis wandering all over the lanes, get a heavier truck, but I found out that when it's too windy for me, semis are having an even rougher time.

I get a sudden push from big wind gusts, and so far, especially when they break between opening of mountain peaks, but have not experienced anything that pushed me out my lane.

I would try to sit out high windy days, or at least slow down.

Even on I-64 on the West Virginia turnpike, I can easily maintain the 60 mph posted speed limits with ease, and that includes not having to brake on most of those lopping curves.

There is a compromise with a long trailer and the HDPP when compared to a HD truck, but with me, it more than make up for the compromise when not towing versus having a HD 3/4 ton gas, including the diesel ..not even close.

Quick Reply: 28 ft TT is really 32.5' Too long for an HDPP F150?
