I just bought a Cherokee Lite 28A TT with a empty weight of 5700 lbs and hitch weight about 575 lbs. I pull it with a 2005 Dodge 1500 hemi. I've only made one trip with it so far to check out the TT and the truck did fine although I haven't pulled up any mountain passes yet. I pulled it in the "Tow-haul mode". The truck was capable of pulling it in the normal mode(overdrive) but it did quite a bit of shifting up and down. It seemed comfortable in tow-haul and that's the way I left it. I don't know how much extra weight I have added to the trailer besides its original weight. But dishes, lawn chairs, etc probally added about 200 lbs or so. I plan to take it to a scales soon, weigh the axles, tongue, and entire rig as described in my TT trailer manual and on this web site. There are a number of TT out there made for 1/2 ton trucks. Some of them will be identified as "lite" as my Cherokee is. Other makes I looked at were Pilgrim, Nomad and Starcraft that had models your truck should be capable of handling.
One question I have for the folks on this forum is: Do you get a noticeable benefit from having a cap on the back of your truck to reduce wind resistance between tow vehicle and TT? I have a open bed and noticed about a 4-5 mpg reduction pulling the TT.
