Congratulations and welcome to the forum!
We love our 17FQ especially the ability to get out of the bed without having to climb over your bed mate. Do a search on this site for great suggestions & modifications other 17FQ owners have made. One of the easiest and most practical is replacing the incandescent bulbs with LEDs. Really cuts down on the wattage draw and cuts heat generation.
Your reduced towing capacity on the Jeep is most likely due to it's shorter wheelbase. I had a Wrangler and didn't like to have too much weight behind me. We've got a Nissan Frontier and even with a 6K tow rating it shifts a lot going over the mountain passes (10 - 12K feet) in our area.
Can't wait for our first trip this year. Hope to be out in Moab & Canyonlands area in a few weeks.
