I'm starting to look for a newer truck to pull my racecar and boat with but I'm not sure what the best choice is at this point. Think I want a 3/4 ton so I want to learn as much as I can about what's available from the big three makers. I know it's a matter of preference and price a lot of times but I want to get the best towing bang for my buck. I'm leaning in the diesel direction but not quite sure. I'm open to suggestions. I want an automatic but I'm a little concerned about what trucks have an auto tranny that will stand the test of time. I know the allison autos in some of the duramax trucks are supposed to be tough trannies but what about Ford and Dodge? Do they offer something similar to the Allison in their trucks. I doubt I will be able to afford a new truck so what would be availabe in a 2 to 5 year old truck?? I'd appreciate any help ya'll can throw my way. Just trying to educate myself as much as I can before I start talking to dealers. Thanks!
