I have the XLR 24 and like it quite a bit. I bought the Extreme Package which has the gas tank which would be great in your situation and it also includes double pane windows and heated tanks. All in all I am very happy with it. Sure, I would love to have a separate garage and a slider and have no doubt someday I will upgrade to a model that has that. The great thing is the shorter ones are quite a bit lighter (1000 pounds) and the tongue weight was nearly 300 pounds less.
Pros: There is even more space in the garage than some of the longer options, the electric bed is fantastic if you add some memory foam as it takes up no floor space, and I find the fold down sofa things actually pretty comfortable. The retractable screen is awesome in the fall. It is shorter in height than many competitors and this became a very big deal when it came to storage for me.
Cons: The bath while functional is quite small, especially the shower. The Queen bed is short, I may modify it to add length and it is kind of a pain to get in and out.
3-5 years from now I might consider upgrading my truck and going to the longer units but for now this is perfect. It carries 17 foot canoe with a kayak on top of it. Two thumbs up from me. You might want to check out the forest river forums. There is a pretty active XLR community in there and most of that would apply to the Cruiser versions.
