Check out Haier brand. Hold more than RV models, cost less than half. If you can line dry, just a washer will fit in the front garage
an you will get less vibration from that location. The wiring is directly above and the plumbing directly behind making that install fairly easy. They are available from Wally Mart and other box stores in a few sizes.
For a different dryer idea:

That will allow room for a top load washer like this:

Most folks I know are not happy with ventless dryer units.
If you know the model of your Creek some folks can give you unit specific info that may be more appropriate.
Hope this helps.
