Love that floor plan too! We ended up with the 3850RL, which is very similar. Biggest difference for us was we liked the pantry better in the 3850, and the bedroom slide is longer, to include the hall from main living area to bedroom and gives you another closet. If you can swing it, the full body paint is gorgeous. We went with that so that going forward we aren't dealing with peeling/cracking decals or black streaks. These are heavy units. Make sure you are pulling with at least a 1-ton or more. Mine came in at 14.4K from the factory. I haven't weighed it yet with our stuff in it as well, although we don't overpack either. I'm sure its coming in close to 16K though without water.
I don't know anything about the Palomino.
