We bought a standalone holder for toilet paper in the bathroom and paper towels in the kitchen - both store easy under the sink.
I added many Command Strip hooks in the trailer. Two to hold keys right where you enter the front door, and several others in the bathroom to hang towels and clothes when changing or showering. they work well and I don't have to worry about drilling or screwing into the walls or woodwork. And we can easily remove them in the future if need be.
Added a 2" foam mattress topper that really makes a difference. My only complaint about the bed is that it is a few inches too short (I'm 6' tall but even my wife complains about it).
Our Aussie grill also mounts to the rear bumper and swings out for use. It really works well for grilling.
We didn't get the outside kitchen, even though I really wanted one. Ironically the dealer showed us three units that met our needs, and the Bullet was the one that did not have the outside kitchen. We still selected this model based on all the other great features and the layout.
