Congratulations, you are going to love it.
Looks like the TV (tow vehicle) is squatting a little and the front end is lifted. It will be good to understand the weight distribution yourself because the dealerships usually just guess and never really check it out on a scale. I have a Cherokee 264L which is a cousin of your RL and I can tell you they are very tongue heavy because there is not much weight in the rear. To summarize, you should go across the scales without the trailer and with the trailer and see how much tongue weight you have and if you are over 1000lbs you should adjust your hitch.
On a happier note, we love our 'rear lounge'. Aside from the limited storage we have no complaints. The trailer handles very well and you should not have any trouble towing it. I took 50MPH crosswinds on the Oregon coast and stayed in lane.
Here is a link to my review of our trailer, it is very, very similar to yours.
