About 2 months ago I bought a new 2018 3.5L Ecoboost F150 Super Cab, 6.5 bed. I bought it specifically to tow a travel trailer. I had a 2011 Nissan Titan Pro 4X. I tow a 7,000 lb travel trailer. The Nissan Titan towed very well with very little sway at speeds of 65, 70, or even 75 mph, even in high winds (30+ mph). I towed that trailer over 10,000 miles with no issues other than losing a vent of the roof due to high winds, and the truck lacking power going up steep long grades (i.e. the grapevine on I5 California). Since getting the 2018 F150 I have towed almost 2,000 miles with much swaying and bouncing. Can't tow over 60 mph without scaring the hell out of the wife (co-pilot and navigator). I've adjusted the front weight bias, adding water weight (tank is in front of the trailer axles), and tightening down on the anti sway control friction control bar. After doing this I still got a lot of swaying, and the wind was only about 15 mph at the time. I just changed the rear shocks to Bilstein model B6 4600 (same as 5100s but no height adjustment) on the rear, but have not tested with trailer yet. I am also going to add another friction control bar to the tow set up. I read on the internet if you have over 26 feet of trailer you should probably use two friction bars to help stop the swaying. I will update this post later if all this works, but it just irritates me that my Titan towed very well and this F150 does not. Other issues include a chugging or un-smooth shifting of the 10 speed transmission. I don't know if this is because the transmission just shifts badly, it has a problem, or the 6 cylinder engine in just a bit shaky in the low RPMs when going through the gears. I just noticed I also have a bulge in the upper portion go the dash on the passenger side. This may be just how it looks or it warped due to heat of the sun. I would appreciate any comments, and will update this post in July after my next trailer trip, and after discussing with the Ford Service Department about these problems. Thanks.
