"Most 1500's don't have the payload to carry that much tongue weight, passengers, and stuff in the bed. Do yourself a solid and get a 2500. You won't regret getting the proper tool for the job."
X2 The trailers you are considering are nearly 33' long and no half ton is going to be enough, as it will be the tail wagging the dog. As noted above watch the payload numbers on any new truck. Dodge is notorious for some of the smallest payloads out there. Crew cab 4 X 4's can have as little as 1,000# and that simply will not solve your problem. Good luck.
