With your Jeep, I would try to stay around a dry weight of 4,000 to 5,000#. That will give you plenty of cushion for towing and give you plenty of trailer for your needs.
Outdoor kitchens are nice. I do all the cooking and do it all outside but I use a Weber grill or a Coleman 2 burner stove. They work just fine for my needs. But really it is up to you.
Consider whether you want a shower only or a tub with shower curtain. That sometimes makes a difference in the floor plan configuration. We have a nice sized shower with a solid door and love it.
Our Freedom Express has two slides, one for the dinette and one on the other side for the stove and pantry and we have a kitchen island where the sink is. Slides really open up the space but also add weight. You have to decide whether the additional weight is worth the additional space.
Good luck in your search.
