I agree with several posts already here that the most important thing is to check the numbers, and assume 12% of the GVWR of the trailer for tongue weight. However, anecdotally, my wife and I tow our 24' bunk house trailer with a 2009 Ram 1500 with the older 4.7L V8. That truck has been terrific and we've towed from Florida to as far away as Arizona and Utah. The truck has been more than sufficient but there have been a few times that I wish I had a little more power. As a result when I retire in a couple of years and look to get a new truck, I'll consider a Ram 1500 with the Hemi, but I will also look to see what is available in the 2500 series. That is not to say I've ever felt unsafe with the 1500, but if I can get a little more margin, I'd go for it as long as I like the truck. If I find the 2500 too big or uncomfortable, I'd have no issue staying with a 1500. My trailer is a bit lighter than yours, with a GVWR of 5,000 pounds, but I do know people successfully trailers in your range with 1500s and they have no problems.
