It should have a towing rating in the manual then compare that to the weight of a TT but a start would 20 to 26 ft unit that should get you in the range

What ever number is published, do not believe it. The number is based on a base model (stripped) truck, no cargo, no hitch, no accessories and only a skinny 150# driver. FOr every pound you add over this base model truck, your tow rating is decreased by the same amount. To know for sure you need to weigh the truck (loaded as for travel and add 150# for a hitch) and get total and axle weights.

GCWR - loaded truck = MAXIMUM loaded trailer weight.

GVWR - loaded truck = MAXIMUM loaded trailer pin or hitch weight.

DO NOT use the trailer dry weights as these are not accurate and do no incluse any item listed as an optio...like, A/C, microwave, awning, batteries, etc. Typically a trailer will easily be 500 to 1000# more than the brochure weight before you add any supplies. Remember that water weights 8.33 #/gallon.

As a quick, get in the ball park approach, use only 80% of the trucks published tow rating and add 1000# to andry trailer weight to see the MAXIMUM you can look at for a LOADED trailer weight.

Some of the new tow ratings are simply unbelievable....over 11,000# for a PROPERLY equipped EcoBoost F150.....I'd say, more realistically maybe 8500 to 9000#.

You have to remember that towingis not only about the power and the weight, but also, is the truck able to handle that huge sail area box of a trailer.

You say towing package is on the truck....there are lots of definitions of towing and you need to see exactly what is on the truck...axle ratio, engine size, cab size and HD cooling. Typically you will want a 3.73 axle as a minimum and possibly a 4.10 axle. You will want the largest block engine you can get.

And last, how much towing do you plan to do and how far.

Remeber, on a 1/2 ton truck, you will normally exceed the GVWR or rear axle GAWR before you reach the GCWR, so the hitch weight become important. The more you load in the truck, the less hitch weight you can carry.

Good advice......... I would go by gross weight of trailer not the empty weight........ the RV dealers always like to down play the weights...... tell them you only want to talk gross ..weights.....

I agree with the above. Also look at what you are confortable with. Some people do not mind pulling a 30 foot trailer and others only want to pull a 18 footer. Remember - you have to stop it too. You might want to go with a smaller trailer for a pleasent trip instead of a white-knuckle hair greying heavy trailer just so you can have a little more room. I pull a 27 footer and love it. It it is only me and sometimes one other staying it the trailer. Oh, and sometimes my dog and best friend Thor.

I have heard not to exceed the 80% weight rule. Most RV salesmen have told me my TV was "enough truck"! Then I spent bucks for airbags and superchip. From 1/2 ton to 3/4 ton is like night and day.

Check the towing specs at the Ford website. Depending on engine and bed length I saw trailer weights approaching 10,000 lbs. How much you actually tow is up to you as no one in an official capacity will give a hoot how much is back there as long as you are not a commercial hauler.

Why do the 3/4 ton users keep throwing up the commercial hauler business? We all know that RVs are exempt from commercial rules, but the laws of physics still apply. The advice is to stay within the publish GVWR, GAWR and the GCWR for the truck.

Going by some of the thought processes often presented here, you can fit 22.5" wheels and tires to a ford Ranger and think you are OK to pull a 40' Teton.

Not enough info to give you a good answer. Ford's trailer towing guide also uses engine, axle ratio, wheelbase (bed length) and whether the truck has the optional max tow pkg and/or HD payload pkg.

Ford's tow ratings use the truck's gross combined weight rating (GCWR) and subtract the shipping weight of the truck with no options, no passengers and no cargo. The tow ratings ignore hitch weight limitations, although hitch weight is usually the limiter on an F-150 that does not have the HD Payload pkg.

For your 2012 F 150, 4 door, 4x4, trailer towing pkg, Ford's tow rating varies from a low of 7,500 pounds for a truck with the 5.0L engine, 6.5' bed, and 3.55 axle ratio, to 11,200 pounds for that same truck with the EcoBoost engine, 5.5' bed, 3.73 axle ratio, and Max Tow pkg. (Your SuperCrew was not available with less than the 5.0L engine or 3.55 axle ratio, so the weakest 2012 F-150 4x4 SuperCrew has the 5.0L engine and 3.55 axle ratio.)

To reach the 7,500 pound number, Ford began with the 13,500 GCWR of a SuperCrew with 5.0L engine and 3.55 axle ratio and subtracted the 6,000 pound weight of the empty truck. So if that's your truck, if your wet and loaded truck weighs more than 6,000 pounds without the trailer, then your tow rating will be less than 7,500 pounds.

To reach the 11,200 number, begin with the higher GCWR of 17,100 pounds for the EcoBoost with Max Tow pkg, and subtract the 5,900 pounds weight of the empty truck.

But for a practical answer to your question, you need to load the truck down with everything that will be in it when towing. People, pets, cooler, spray-in bedliner, toolbox full of tools, extra jack and jack base, any extra fluids such as motor oil, ATF or antifreeze, shank and ball mount for the weight-distributing hitch, or 5er hitch installed. Go to a truckstop that has a CAT scale and fill up with gas. Then weigh the wet and loaded tow vehicle.

Subtract the weight of the wet and loaded truck from the GCWR to get the max weight of any trailer you can tow without being overloaded by exceeding the GCWR of the tow vehicle.

Subtract the weight of the wet and loaded truck to get the max hitch weight you can have without being overloaded by exceeding the GVWR of the tow vehicle. Divide the max hitch weight by 15% to get the max travel trailer weight you can tow without being overloaded over the GVWR of the tow vehicle. Divide the max hitch weight by 20% to get the max fifth wheel trailer weight you can tow without being overloaded over the GVWR of the tow vehicle.

Ignore anyone who advises you that it's okay to tow overloaded. It's not okay.

Work the numbers, the tow rating is the lower of:


1. GCWR minus RV's actual weight (if it's not over GVWR).


2. Hitch capacity.

You can always go by my wife's formula.........."I like this trailer, the colors are nice, it has a slide out, and it is the one I want and I have seen other SUVs towing trailers like this". LOLOLOLOLOLOLOL

Egg-sactly Bill - VERY scientific and verifiable formula as my wife has a variant that includes blows amongst my head if I disagree
