Laurajune, this dish drainer, that is made for RVs, works great for me. It fits very well between the sink and wall in our A126.
This photo shows the little drain hole where the water drips back into the sink:
And it stores for travel nicely under the sink. I have more room under there with the water filter gyzmo eliminated. I am very cautious when it comes to leaks. It looks crowded, but is actually lightly loaded with plastic dishes and cups, etc. The fittings and lines on the lower left have only a few hand towels and wash clothes stored on them. I use pencil baskets to keep spices and other things upright and orderly. Never put heavy objects or pressure on/against any of the fittings or water lines.
Hope this helps,
