I did quite a bit of research before I bought a new truck to pull my Yenko to SCR7. I decided on a Chevy Silverado, 2500HD, 6.0litre gas, crew cab, 4WD, tow package, etc.... all the goodies. I pull a 24foot Haulmark Elite II Race Trailer which weighs about 4800lbs, and the Deuce at around 3500lbs, for a combined weight of around 8500lbs with me and some junk. This truck is rated to pull 10,200lbs with the dist hitch.
Bottom line: I love this truck! It pulls just like my 'advisors' told me it would over the steep Apalachians - especially the two biggies in WV. This vehicle is a compromise of course, it has to serve as the 'mini-van' for the family, the hauler for the home projects, the trips up steep, washed out, logging roads for deer hunting, and tow vehicle.
So far, excellent.
