Thanks for the kind compliments! Yep... the fans and the chrome grilles came from http://www.parts-express.com ... great source for all kinds of stuff.
Since these photos were taken, we replaced the faucet with one that we find perfect for the way we live (and wash dishes) in the Casita... the spout-thingie pulls out... see it here (and forgive the lousy photos!)...
great Job.......that is a super clean install! any info on the lights?
Yes... The lights came from Camping World... they even have the clear (I think that they are polycarbonate) lenses that fit the Casita housings perfectly... pretty inexpensive, too!
