Hi RoccoJohn,
I did the research on this just like you are doing. Way to go, it will pay off. I personally use a Chevy 2500 HD Diesel to tow a 28 foot CCD.
Glad I have it, it's a great combination. Lots of people state the 1/2 ton trucks will do fine. I don't have any experience with that but it makes sense. I just like having the extra capacity.
Good luck in your search. This topic always brings out the politeness and thougtfulness of the Chevy/Ford/Dodge/Toyota/Nissan pick up truck owners. We are a very pensive bunch who never react too strongly.
I kid of course, a lot.
John
