HD trucks are potentially a false sense of security when it comes to dynamic handling. Ballast does not help in that situation...

70-0 braking distance

F250 Diesel 4x4 - 202ft
F150 EB 4x4 - 175ft

It would be interesting to see braking distance tests between those two while pulling a trailer.

No, it wouldn’t. Nothing about hooking up the same trailer to each truck improves the F250 braking distance compared to the F150. This is just basic physics.

What may come into play is the fade resistance. So, an unskilled driver, descending too quickly for their rig, overusing the truck brakes, and not utilizing the trailer brakes properly, could have more safety margin with the heavier truck, until the brakes eventually fade. As they will.

Or, they could drive properly.

I think this statement is just plain incorrect.

The 250, by virtue of its extra weight on the tires, will provide more braking for the combined rig than the lighter 150.

The Ferrari SF15-T weighing in at about 1,400 lbs stops from 70 mph in less than 50 feet. It's all about mass.

If the heaviest thing stopped the fastest, then cement trucks would be kings of the road.

No, the extra weight on the wheels of the F250 is more than offset by the increased mass. You have four relatively small tire patches on the road...

No, the heaviest thing does not stop the quickest. In fact, when you do the math for stopping the weight is in both sides of the equation and cancels out. Stopping distance is related only to tire traction and of course if you have enough braking power to use the traction.

But...when you hook up a trailer the numbers shift. Say a 6000 lb trailer with 1000 of that tongue weight. The 1000 lbs tongue weight adds that much down force to the TV for braking and cancels out. But the remaining 5000 lbs weight drives the rig foward without adding any braking force. You are essentially doubling the force forward without adding any down force for braking. So when you are pulling a trailer the TV weight does matter and more is better. If you have enough braking force to use it.

Now, if you really believe the TV stops the TV and the trailer brakes stop the trailer then, yes, the weights are irrelevant and the total rig stops in the same distance as the TV alone. I have 10 inch electric drum brakes on my trailer. They do not do the job alone. The wiring comes loose. They overheat and fade. You could stop a trailer fine with the Ferrari if the trailer has hydraulic disc brakes that work as well as the car. But with my trailer the Ferrari just might end up sliding along in front of the trailer for a spell.

On a side note, there is no such thing as "simple" physics.

Bill M. must have read the Dexter Brakes Not Working on One Side of a 25 foot International.

Towing is one matter. Anything that has a 2 inch hitch probably can pull a trailer. It is the stopping that is an issue. When your tow vehicle's tires are locked up and leaving tire rubber at the intersections (although ABS rules today)... it is WORSE. Try some snow on the road, braking with trailer in tow.

We are all helpless in ice and snow. Even a wet newly asphalted highway can give you goosebumps.

You will have braking power and the rear end... dragging power. Works for you, great. I am not a mathematical genius... although having good judgment is a better trait of living longer and with less stress.

Many prefer to fill the fuel tank to full. But if your setup is overweight, do you only fill the tank 50%?

I am not convinced that I should give up my F350 Diesel Rivet Popper just yet. At may age longevity is my current plan of attack to save on Estate Taxes. Not because I am towing with a beast, but my biological clock is at 80% used up. So, what the hell... if I keep my F350 and exercise it and myself... I may beat the odds.

I do not guarantee anything I post. I am old, mostly senile and developing a crabbier point of opinion. So... we are leaving for our FREE Casino breakfast in ten minutes. I will feel better... if the food is as good as they claim.

Did not read it. Did crawl under my trailer 2 weeks ago in Nebraska as we were headed home and found both brakes with broken wires on the curb side. I had noted diminished braking power and a slight pull to the left when braking.

Hi

Indeed some Airstream tires are rated to a lot more than 87 MPH ....

I very much doubt that the *brakes* an any Airstream are going to make it down from 87+ MPH without a bit of fade.

I never had a brake failure in my life, but since I've owned Airstreams I've had two of them. One occurred when I lost a tire. The tire debris damaged a wheel well and severed the brake wire. The other was a failure of the Tekonsha brake controller. Make sure your tow vehicle has good brakes that can step in when needed.

Trailer tires are indeed important. Your tow vehicle's tires, the rears especially, are probably more important. Keep them inflated to the maximum. Also get a TPMS for all your tires.

When all said and done I still think a well set up F150 will stop and pull a Airstream just fine. But I also think that a F250 will do it better and last longer while doing so. The trade off is between driving empty and actually pulling. Gas or diesel. Personal choice. I pull with a 2500 diesel.

This is what AS President has to say about tow vehicles.

Jay suggested a 250. Bob said yeah - or the F150 which is a favorite for his customers. He also said the weight of that LandYacht was about 6200# (that’s surely dry, not loaded) and since an F150 doesn’t weigh 9300# (1.5x6200) I’m not seeing where AS is possibly making a recommendation of 1.5X the weight of the trailer. Maybe there’s a 1.5 ratio somewhere but not between trailer and TV weight as far as I can see.

One has to wonder how many trailers Airstream would be selling if they only sold them to customers with properly sized tow vehicles instead of anybody with a small vehicle and a weight distribution hitch.

Fortunately, at AS there are people who understand how towing works and apply a "proper" logic to their business.

Tow Vehical

The Ford F-150 eco boost. is more than enough to tow and it has the new backing up assist. It handles over 11000 lbs tow capacity and is great on fuel. I have the 2011 and it pulls my 25’ excella with water and as much as my wife can think to pack. And I can barely tell it’s behind me.
Happy trails.

We use a Ford Expedition Max to tow our 27 FB Classic.

We got rid of our ‘16 F250; wecouldn’t stand the bouncy, punishing ride when empty.

The Expedition is so much more comfortable, and tows just fine with its EcoBoost engine, even in the mountains. Mileage without the trailer is 17-20, with trailer around 8 mpg. And the Expedition is easy to park and back up the trailer, as opposed to the long turning radius of the F250.

You should pay attention to the axle ratio!!!! A 410 is way overkill for a lighter trailer and will cost a lot more in fuel and wear and tear on the engine, I tow for a living and have a 373 rear end which allows me to really get up and cruise on the highway and I can maintain my rpms up almost any grade by locking out my overdrive for the relatively few miles I m climbing a grade
