Tom, got the 6.5 bed with off road package. I don't know if it the shocks with the off road but this truck just bounces with the boat over bumpy roads espec on highway. There is no way this F150 handles the boat as good as my SD. I had a 172in WB on my SD and never even felt the boat bounce like I do in this F150. Just me but I just have to accept this trucks characteristics under tow. Didn't think a MaxTow would be so touchy.

 

Huh, that's interesting. The only boat I tow is my little 18' Larson that weighs around 3,500 lbs, and my big trailer varies between 4,500-12,000 lbs depending on what's in it. The shocks on these trucks aren't known for being spectacular, and that's the first place to look if you are having a bouncy ride. You can get some adjustable Rancho 9000s for less than a couple hundred dollars. Might be worth a shot!

 

How are the tires on the trailer? Mine bounced my old truck (2003 2500HD) like a friggin superball until I replaced the tires.

 

I would check the trailer and make sure it has radial tires. Lots have bias plys. Make sure the surge breaks work, pulling 9k is work for your truck stopping that is not some thing you want to try to do. Go slow leave yourself lots of room, it will do fine. In my 2010 fx4 5.4I pull my 7900 boat with trailer weighed at station, and I do fine. I keep my truck in great shape and the trailer too. I would also look into LT tires for the truck depending on tongue weight and load in the truck your P rated tires might get a little squishy.

 

You might be right, I only wish there was a tow/shock suspension button to adjust shocks from normal driving to tow/haul when you hit the TH button.. Guess I can always ask Ford to include in next gen F series!!

 

Until then you could put on some rancho 9000's. they are adjustable from in the cab.

 

You found it!

I did some searching around this morning and couldn't find the MyRide, I thought they discontinued it or something.

Isn't the 3.7 limited to about 6,000 lbs? Heck with a 2,000 lb trailer a eco 4x4 scab with 3.31 would be overloaded on that setup since it is only rated at either 8300 or 8600. Cant remember, but definitely under 9000.

 

Yes, the 3.7 is limited to about 6k lbs, depending on body type.

For the OP, please note the weight you found online for that boat is the dry weight of the hull only. It does not include even the engine in the boat. So the towing weight on that rig will be close to the following:

7240 lbs - hull dry weight
2100 lbs - trailer weight (assuming aluminum tri-axle trailer for 27 foot boat. Would be heavier if the trailer is steel)
950 lbs - boat engine and drive (assuming MerCruiser 6.2L, which is the factory standard for that boat)
610 lbs - fuel (100 gallons of gasoline)
275 lbs - water (33 gallon water tank in boat)
500 lbs - misc. stuff in the boat (gear, refrigerator, etc.)

11,475 lbs - Total

You're borderline with the EB and Max Tow package. You can knock off a few hundred pounds by not towing full of fuel and emptying out the water tanks.

 

I'm pretty sure this is incorrect. With the exception of outboard-powered boats which frequently ship without the engine, every boat spec I've ever looked up is with the base propulsion system. And for my 18' Larson it's very accurate, with the measured weight on a certified scale darn near exactly what my estimate was when I factored in a 600 lb trailer, some gas, and some gear. If the dry weight was without the engine my boat would way 1,000 lbs more, and way over the weight limit of my minivan's towing ability.

I would say worst case scenario he's looking just north of 10,000 lbs. Which really doesn't matter a whole lot anyway as long as there is enough tongue weight, the truck isn't over GAWR or GVWR, and the trailer brakes are functioning as designed.
