I pull our 1993 triple 42 on a Myco with a 2008 GMC ext cab 2500 4x4 duramax no sway or issues. I pulled it from Lake of the Ozarks to Grand Lake this year and was surprised how easy it was to trailer. Truck is stock other than 20's and Nittos.

Those with 35 or 38s, will a F250 Superduty with a V10 pull ok?

I pull my 35 with a 2500 HD running the 6.0, it burns a lot of fuel but no other issues. It is all that truck wants coming up the ramp though.

I think you all are exactly right I'm leaving Richmond Va. heading to Quebec. It's to damn far for that little truck!

Congrats on the new boat though

I pulled my 02 38 Lightning with a 97 F150 for a year. Super charger and airbags helped. Trailer has disc brakes. Definately kept it local but it towed excellent. Got about 8MPG and a lot of WTF's. I finally got a 1T diesel. I think it towed so well because of the trailer (aluminum Myco) and how I set the bags and tongue height.

Thats wayyyyy to much boat for that truck. Thats the reason I went with a 42 a few years ago. You need a 650 or better and I say gooseneck. Have it moved by a larger truck. If anything happens you're SOL cuz you're insurance company willlaugh at you and deny the claim

I would check the distribution of the boat's weight on your trailer. Sounds to me like your not balanced or you have a budget trailer. Not trying to insult you in any way, but there are inexpensive aluminum trailers out there that are not engineered (believe it or not) properly. Your axles could be out of alignment too. Measure that distance from the end of each frame rail to the axle on both sides. If you are "pullin' it in style" with a Myco, please disregard my post completely! LOL
