Those slides sure are nice.
I was going to do the kitchen slide out by putting plastic slider feet on the frame so it slides on the carpet floor of the storage bay. I'd hold it up with 2 legs outside the storage bay. Maybe I need to reconsider this.
However, those slider units only allow the slide to be extended 2/3rds of the way out. About 60". My sliding system would allow it to be extended the full 90 inches. I could also have a second set of legs on the slider end so it could stand independently from the trailer.
I thought about the dorm style refrigerator. Wife says we don't need one outside. Not sure what to think of that.
Now that I've seen the sliders, I'm considering one for storing the rest of the stuff in the storage bay.
