Largely I agree with the other posters. And nobody even said anything yet about how hard that thing will drink gas with that in tow. Not a doomsdayer here it will do it but would not be the optimum TV for lots of cross country towing with a boxy 33, plus well over 8,000 pounds wet. So you can buy the trailer and move it but will likely later upgrade your TV.
FWIW I tow TTs mostly Airstreams commercially with a Ram 1500 ED. With tune it has the benefit of 70 foot pound of torque over the stock Hemi plus a valuable turbo brake for when that load is pushing you down a mountain not to mention use half the fuel. All that said its still a lot for the 1500 platform. Factory hitch receiver with WDH is rated to 1,290 pounds on the tongue.
You would need a good WDH set up at the scales. If you don't have factory air suspension you would benefit from airbags such as TLC, Timber Grove, or Airlift. Also upgrading from a passenger to a load rated tire will firm up some wiggle.
Daryll was yours an 8 speed with the 3.92?
EDIT MO yea a good WDH set up at the scales should keep you below your 3,900 axle weight ratings or 7,800 combined. I have seen CVWR also important as high as 15,950 on a Ram 1500 but even with the trailer brake controller I wouldn't want to have that pushing me down a mountain without the help of a turbo brake. But if your truck is 6k and trailer 8.5k your at a CVWR of 14,500 which is ok.
