Should We Put our Washer and Dryer Outside?
When I was stationed in Panama our gov't quarters included the washer and dryer outside. The term eludes me now, but our quarters we're raised so that the driveway went under the domicile. The washer/dryer sat on a cement driveway under the quarters, exposed to the Panamanian elements.
Lint collection consisted of a plastic box that attached to your exhaust hose. The lint and exhaust went through the box and the lint was caught by wire mesh. 
We actually bought the washer/dryer combo from the gov't after three years of our use. Contractors told us at the time the combo was at least ten years old. I paid $10 for both.
Then I sold them again three years later.
So, to your question, I'd say yes.
Good luck!
