Welcome Diana!
California, huh? Well, greetings from a fellow "Left Coaster"!
Casitas are great little trailers! Well laid-out & well-built from what I understand. Plus, since you're in TX you can actually go get it without a lot of hassle.
As Cedar said, she's got a Chalet. You might want to take a look a them, too, as you might find towing them to be a bit easier on your 4Runner -- less wind resistance. I haven't compared prices & weights lately, but they might be comprable in both areas. Plus, if you're using it for short trips you might find that the larger Chalet will suit your needs as well as a Casita.
We're a very ecclectic bunch by way of rigs. Everything from a Chalet to a big Class A. I'm on the smaller side, too, with a 19' Shamrock hybrid trailer. Again, depending on your needs you might look at those, too, especially the smaller ones.
I'm in the L.A. area. If you get your rig let me know -- we'll go camping!
Laura -- and Jed
