I tow my 220 Sundeck with a Ford F-150 Fx4 5.7L with tow package and 3.55 rear end. Trailer has 2-Disc brakes. Tows great but you'll know it's back there when you hit the hills...Locking out OD is a must. Other than large hills, I can cruise at about 70mph. Once I move to a bigger boat I'll have to upgrade the truck as well.
I towed mine with an Expedition with the same 5.4 and 3:555 gears. I was surprised at how much difference the right after-market exhaust and intake made. I also ran a chip (an actual Superchips "plug in" chip since it was a 2000) which the primary benefit was tranny tuning (I also installed a shift kit). I ran the Gibson Swept Side single exhaust, and an Airaid intake. Obviously you could tell 7000+ lbs was back there, but I never locked out OD and it ran great. I also for 11-13 MPG which was 3-4 MPG better than friends with a similar but slightly smaller boat got in theres. I also tow conservatively and 60-65 and still do.
It had no power problem, but I knew I was at the ragged edge of the Expedition with the 240 which is why I got the Excursion. But there are things you can do.
