Re: Neal's Moen Faucet Replacement (was Re: What did you do to your coach today.)

I replace leaking Delta the kitchen faucet in my 1996 U320 three days ago - took all day because I also replaced the water filter with the $45 cartridge. I installed a standard house one which has $10 cartridges. In addition to this I installed a "T" in the hot water line and ran a pipe to the water tank for a "get hot water to sink" without dumping water.
The shelf and drawer was just as you described - it was awkward - required a mirror and trouble light, as well as innovative body positions, but do-able without removing the shelf.
I would look for another plumber, or an unlicensed handy man. Replacing taps does not require an experienced plumber. Note that I had to extend the plastic lines under the sink because the pig tails on the new tap were shorter than on the old tap. This requires cutting the bands off with a Dremel and using screw clamps.
