So I am looking at a new 2016 F150, with a 5.0L, with 3.55 ELECTRONIC LOCKING AXLE. I have a 28' Travel trailer weighing about 6200lbs, curious is the 5.0L strong enough to pull it or should I be only looking at the 3.5 Ecoboost max tow

Ask the dealer to let you test tow with both

 

Hi,
Get the 3.73 gears as this will pull a house. Also get the 157" wheel base as it is a lot more stable when the semis fly by.
I had a 2012 with 3.55 gears and traded it for 2015 with 3.73s, huge improvement, tows 10,500 lbs. now.

depends on how much gas you want to burn, eco will out pull and out drink the 5.0.
for that weight the 5.0 will do great

 

i get 10mpg pulling 9k boat couldnt be happier love the low end torque. 3.5 EB

 

I would agree 3.73 gears and 157"WB will help.

 

The 5.0 will get that job done.

 

I have the same setup with my truck and both the boat and trailer weigh in just a tick over 7,000 lbs and it pulls without any issue so you should be fine.

 

I believe with EB 3.5L you can get 3.55 but 3.73 ratio is only available with the 5L. 6200 lbs is not a problem for either motor with 3.55 or 3.73. Max tow package does add limited slip.

 

Either engine will do your job. Even the old 460 Ford big block had around 250 HP and 400 ft-lbs of torque, and the International Harvester 345 V-8 used in grain and dump trucks had 182 HP with 303 ft pounds of torque. The EcoBoost 3.5 has 365 HP with 420 ft-pounds of torque, while the 5.0 has 385 HP and 387 ft-pounds of torque. As far as the engines go, it is personal preference.
Payload will be your biggest concern. A 6200 pound trailer (unless it is a boat) will have about 740 pounds of tongue weight, and your weight-distributing hitch will weigh 75 to 100 pounds. So, you will use up about 850 pounds of payload before you add people, luggage, aftermarket accessories, and cargo in the bed of the truck.
If you have 4 adults in the truck (say 800 pounds), a tonneau, bedliner, and mudguards (say 200 pounds) and your trailer, you need 1850 pound payload before you load anything in the truck bed. Many loaded-up F150's won't have that much payload.
