Thanks for all so far.

There is some talk of Headhundter Toilets which I think are supposed to be the best ones. My 97 has a Microphor which I"m not very happy with. If a redo of the water bay going to provide a good time to upgrade to a Head hunter brand ? I don't konw if I want to go so far as tearing into the holding tanks I'm mainly wanting to update the exterior access bay. I'm ditching all the filtration and levers and cooper that go with that and will put something more usuable like an electric pressure waser pump or a hose reel. My bus doesn't even have a good palce to put the waste hoses. I could make storage for that maybe.
I nicer faucet maybe, stainless trim. I'm in Central Florida. Is there anyone around my parts that would be good to look at what I'm trying to do and help size up a draiwing for me to go work on ? Or am I save just tearing into it and using logic. I don't want to get tripped up accdiently and you guys no so much more about these things. Can I wing this and figure out w/o fear of any pit traps that will get me ?
