It's a new RAM 2500 so the receiver darn well better be up to the task. In years past manufacturers put underrated receivers on heavy duty pickups, but both Ford and GM put decently-rated receivers on their big pickups now. I'd imagine Ram would follow suit.
How does it handle? You've clearly driven it, so if you don't feel like it is handling poorly, then it probably isn't. Even so, WD wouldn't hurt, and neither will some sway control, just in case. But it would be optional.
Make sure the receiver is rated for the weight, and the shank/ball combo is rated for the weight. I've noticed that most camping stores and places like Walmart only sell 5000-6000lb rated shanks, which isn't enough for this trailer.
I've trailered a couple of tractors with my truck that took much more off the front wheels than 270lbs and the rig never felt like it was going to be a problem.
