Not sure what your galley counter configuration looks like since I don't have a
Scamp, but in my
Casita 17' SD, I couldn't stand that little "bird bath" of a useless sink that it came with, so I ripped it out and installed this one instead. Here's the write-up of my project that I posted on the
Casita site. FWIW, hope it helps or at least gives you some ideas for something actually useable.
(From my
Casita site post)
"Well, I just had enough of the small, relatively all-but-useless, galley sink that came with my trailer. Since I have the SD model, I didn't have enough room to install a standard 15" X 15" sink which are commonly available everywhere. I had to look long and hard to find one that was deeper, longer (front to back) and still not any wider than 14" which is the maximum space between the
microwave cabinet bulkhead and the stove. I finally found one that was twice as deep, two inches longer, (front to back,) and basically the same width as the existing sink. It also comes with a 3" stainless steel drain and a swiveling 6" high goose-neck faucet assembly, which directly connects to the existing 1 1/2" drain line and the existing PEX hot and cold lines without having to do anything more than whack off about 5" of the vertical drain pipe in the cabinet under it. After removing the old sink, taping over the hot & cold PEX pipes to keep debris out, and "templating" out the rough opening cutouts that I would need to make for the new installation, I got out my Roto-Zip and had at it.
I won't say that this installation was easy for me, since I couldn't fit my large carcass into the cabinet under the sink. It was all reaching in as far as I could and most of securing the sink clips and hot and cold lines was a "mirror job" with the use of many improvised tools, but despite the fight I had with doing this one, it's in!
The (4th) picture, with the white paper plate in it, is showing how deep it is. That's a 10.5" diameter plate!
The new sink is made by Krowne, and is their Model HS-1419"
