You can't go wrong with a Dodge, depending on the size of trailer you want you may wish for a 3/4 ton. We started out pulling a 31 foot airstream with a 1/2 ton and while it did the job I never was very comfortable. We traded in and got a Silverado 2500 HD
4X4 and man what a difference with the auto loc differential and the 4:10 rear end it is a great tow vehicle. Fully loaded the trailer wieghs about 7,500 lbs and while I know it's there I am very comfortable on the highway.
