The manual the truck came with says, 5.4L with 17 inch tires Rear ax 3.55 Max GCWR is 14000, Max tralier 8000. On the door plate below the barcode this is there TP/PS R(6) Axle (B6) TR (Q). DSO SPR 7F615 SSRR DO5.
On the rear end plate reads V913C, 739757AO8.
Can my truck tow this tralier with no probum. I have had it out a couple of times but I worry every time I go out and that dosen't make for a very good trip. I am planning a trip to Yosimite this summer and just want to be sure.
Thanks you for your help
OK, something ain't just right here.
1st of all, with the axle code of B6, you should have 3.73s with traction lock.
I can't tell from the picture whether that is 4x4 or 4x2, but given that your GVWR of 7050 lbs., I will presume that you have a 4x2. The 4x4s came with a 7200 lb. GVWR.
Looking at the chart here https://www.fleet.ford.com/showroom/...trp16May07.pdf
, for a 2007 F150, 5.4L, 3.73s, and a 144.5 wheelbase, you should have conventional towing of of 9500 lbs., with a GCWR of 15,000 lbs. They are some really good numbers.
You need to be sure that your truck came with the heavy duty tow package. Usually, a call to your local Ford dealer with the VIN should reveal that, as well as confirm your final drive ratio.
If you do not have the OEM heavy duty towing setup, then you will need to add a auxiallary transmission cooler, and make sure the hitch is up to pulling that kind of weight.
You did not list what model trailer you are pulling. The 144.5" wheelbase of the truck is good for fairly long trailers, but a weight distributing hitch with integrated sway control will probably be better than a conventional WDH with friction bar sway control. If you keep that system, you may want to consider adding another friction sway control bar if the trailer is over 27' or so.
The limiting factor to all of numbers is the 1/2 ton pickup itself. You have done great in adding up your passengers and cargo, and coming up with 1400 lbs. But you have to add the tongue weight of the trailer into that formula, also. Hang a 800 lb. tongue on your hitch, and that 1400 lbs. now goes to 2200 lbs. You may need to carry some of the stuff you plan on carrying in the bed of the truck in the trailer, since you have a fairly high cargo carrying capacity there. Weighing the truck and trailer loaded for camping should be 1 of the 1st things on your list when you get hooked up.
Like Bob had, I have a similar truck setup pulling a 5500 lb. 28.5' Surveyor, and it does a great job.
