You'd better be careful! When he sees you sitting in the coach salivating
over the manuals, you ain't a gonna make no swift deal! But it sure is fun,
isn't it?

Best regards,

Travis

Chris,
This sure looks like mine did when I got her last year. The plaid seats and
shag carpet kind of grow on you after a while :) Makes you feel real like
a 70's kind of guy! We will be replacing ours in a few years however.

You have the infamous electric recirculating toilet. A lot of folks love them
and
lots hate them. The way they work is that you put about 3 gallons of water in it
along
with a double dose of holding tank deodorant as an initial charge. Then you use
the toilet. Each time you flush (which is done with a push button on the left
side),
you recirculate the stuff in it until it either fills up (about 7 gallons) or it
smells too much.
If you plan on doing a lot of camping where you are not connected to a sewer or
sewers are few and far they are great. If you can dump your holding tank on a
regular basis, then a standard RV toilet is better in my humble opinion. This
kind
of toilet was an option that cost more when the coach was new.

My wife hated the recirculating toilet. She thought it smelled and she hated the
idea
of using someone else's 23 year old toilet. You'll also notice that the bowl is
black so that
when recirculating that stuff, it's harder to tell what it actually is.

I ended up tearing it out and installed a very nice new toilet with a porcelain
bowl. It
was about $200. I thought it was a cheap way to keep the wife happy.

A nice upgrade is a new headliner. There are many ways to do that and the folks
on
the GMCnet will be happy to help you decide how to install a new one.

Chris,
just my 2cents from my own experiences.
When I started chasing down leaks as part of changing to synthetic oil we
found that a large mess was caused by a bolt/stud that holds the waterpump.
Even when just slightly loose it mad quite a mess that eventually collected
around the oilpan.

What I really mean is that some 'very' small leaks can make it appear
serious. As part of chasing it we used a UV kit to be sure we had no cracks
anywhere.

As a regular post-flight I now check waterpump bolts, exhaust header bolts
etc.

Unfortunately it'll take some real miles to shake it all out. Even when mine
sits for only a few months the first trip is always not quite as nice as
subsequent ones with shorter 'parked' periods.

Good luck and enjoy
