Hi Texan,\
The following is excerpted from my post on August 26th, 2012 "How to install a sink in a FWC" as follows:
"...The installation is pretty easy. A pattern is included. Locate the pattern on your counter, scribe a line around the pattern, cut the hole with a portable jig saw. Included in the kit is a roll of plumbers putty. Lay the putty around the hole . Set the sink down into the hole and tighten down the clips. Trim off the excess putty with a sharp knife. Sink is installed.
Drain and connection to outside:
FWC includes the outside plate and a length of 3/4" heater hose. ****Drill a 1-1/8" hole from INSIDE to outside. and make a 3-4" square backing plate to bolt the plastic pipe flange to the inside of the camper as a "sandwich".
Buy the drill at a hardware store or Home Depot/Lowe's. The unit is round metal with a jagged face and a regular drill in the center. The OUTSIDE hole is just a little larger diameter than the 3/4" heater hose. The hardware store employe will help you choose the correct size drill to accomodate the tube. Don't drill the OUTSIDE hole too large as there has to be enough aluminum to run the screws through to create the outside of the sandwhich.
If you are uncomfortable doing this take your project to a handyman or Camper service store, pay a few bucks and have it done right.
******The primary issue with drilling through the side of the shell is the location of the vertical studs. FWC uses two frames - one setup for shells and one setup for campers with the full kitchen. I was unable to obtain a diagram of stud placement and a normal stud finder didn't work....I said a prayer and guessed.... and was almost lucky just clipping the edge of the stud (If I had drilled the hole directly inline with the pipe coming out of the sink drain I would have squarely hit the stud). I expanded my hole over to the right about a half an inch then drilled through the aluminum plate and easily installed the flange increasing the size of the backing plate to 3 x 3 inches to cover the hole. Shortened the heater hose added a hose clamp and was done. "
I would contact Terry at FWC BEFORE drilling the hole to get advice on figuring out stud placement as he might have a diagram for your camper. You can cover a mistake on the inside with a block of wood...NOT the outside so take your time and don't rush the process.
