Any new guys out there looking for improvements to the GMC coach, listen up; The best improvement you can make to the coach is to install a macerator. I put one on about 20 years ago, and have never used the 3" hose again, while camping. We can go two days before dumping, when not trying to conserve water. (We both shower everyday.) Then I pull the 3/4" hose out, and turn on the switch. The best way to handle the 3/4" hose is to put a 1" pvc pipe under the coach, and just stuff the connected 3/4" hose down it after capping it. I never unhook it. I used a 25' 3/4" hose, cut it in half, and keep the cut off end in the storage compartment for when I need more than the 12' length. I don't mess with either of the slide valves while traveling, just cap off the 3/4" hose when in storage.
No dirty/unsanitary hands, no big messy hose to deal with, and very simple operation. No leaks, spills, or drips ever! I still carry the 3" hose for an emergency, but have never had to pull it out on the road, only back at home when flushing things after a long trip or when we lived in this thing while building our new house.
Best improvement EVER for a GMC coach, bar none!

I'm gonna start a new sub-group called the GMC Luddites. We will defend our carburetors, gate valves, OEM cruise controls and floor mounted headlight dimmers to the death. I will probably be thrown out over my 16 inch wheels.
I actually have a clip - on macerator which fits in place of the cap on the 3 inch outlet... best of both worlds. I haven't bothered to run power for it, it's just a non-issue to me. Some years of picking up at dog shows and RV parks after a 125 pound dog or two has inured me to opening the gate valve and closing it every four days or so. The macerator looks like one more thing to break, and if it's permanently mounted, one more thing to break underneath my coach. When the patches on the black tank finally cover more than the original material and I have to replace it, I'll revisit the idea of a macerator.

Yes one of the best things (if not the best ever) I have ever done was install a macerator. I did that back in 2001. I did pretty much the same thing with the 1" PVC hose storage, cap for storage and 50' 3/4" rubber hose cut about 40' to dump at home and 10' as an extension stored in the pod.
Here's a link to a page I did:
http://www.palmbeachgmc.com/macerator.htm
I really miss Denny Allen.
I absolutely would never go back to the old way of dumping, except maybe when camping long term with a sewer right at the coach. I don't know much about the clip on macertors, but it seems like that might be almost as much a hassle as the 3" slinky hose.
I have had zero problems dumping. I really enjoy pulling up behind someone at the dump station and watching them struggle to dump. Then when I pull up and dump in a matter of minutes, if someone is watching me, I get the inevitable comments about what a slick way to dump.

I'm a firm believer in if it ain't broke don't fix it. But when it breaks I'll look into all the options. As long a the carb works I'll stick with it. If it fails or I need to do a major overhaul to the fuel system, I'll consider TBI. Like you the 16.5" rims had to go. Too much risk in not be able to find tires in an out of the way place.

While Corley has a point, let me tell you (from peronal experince) that, if you plan to install a macerator, plan to remove it with the black tank full. How you accomplish this is little concern (to me personally), but I have had a lot of experince with other people's macertors. You will not find out that it has problem until you need to use it. If you set up a dump for three inch hose, you don't need to carry one. You will probably be able to borrow one if it is needed.
The thing you absolutely have to carry is either a spare unit or a complete rebuild kit. This something that you may not be able to acquire locally when you need same. There only a few manufacturers, but which is available where is carp-shoot.

Matt... Not so. The macerator is setup as a 'T' on the main 3" line. If the macerator should fail, the 3" hose works just fine without taking anything apart. (But mine has never failed in 20 years...) There are two valves, one at the tank, (I leave that one open), and one before the 3" pipe exits (I leave that one closed). Attach the big dirty/messy hose, open the second valve, and out the nasty comes down the 3" hose. If you ever need to work on the macerator, dump the tank using the 3" hose, flush it well, close the tank valve (for protection  )then attack the problem without having to take any of the big pipes / valves apart. It's the best of both worlds.

Leaving the 3" dump system in place as a backup takes care of this. One
of the first things I did on my coach was install a Denny Allen
macerator kit and 11 years later I haven't had to use the 3" dump once.
I've removed the macerator one time, purely as a preventative measure.
I'm with Corley - best thing ever. It's possible I'm a bit more
squeamish than some but I'm just not a fan of the 3" slinky and all the
stuff that collects in those corrugations.
Half of the reason I bought a GMC was because that kit was available. :-)

Besides keeping the 3" dump functional, I also carry a spare macerator. In addition, I also store two 3" hoses with couplers for the rare times when camping where there are full hookups.

Corley,
Thank you for confirming my point.
If you read what I wrote, you would have noticed that I wrote, "plan to remove it with the black full." Not, "when the black tank is full". There is a semantic difference there that is important.
As you have a macerator that has never needed service in 20 years, I suggest you buy all the lottery tickets you can before your luck runs out. Actually it isn't so much luck as fortune - bad fortune. Things (stuff that ends up in black tanks) happen. Like the plastic spoon that a clients daughter accidentally lost into the pot and didn't happen to mention to her father. The locked up the pump and took the impellor out in fine style.
Oh, and that valve you haven't closed. If it is original, it is a Thetford "Slide-EZ" that I know very well. Don't close it now. The rubber seal will probably peal out and it will never seal anything like drip tight.
I am not opposed to macerators. I just never want to have to fix one again. Now, if we were to move from a home with a dump port next to the driveway, I might consider it. But, it has been arranged that I can't sell my house for more than what I paid for 20 years ago, I think we will stay a while more.

Matt:
HUH? What does "with the black [tank] full" mean to you? To me, it means the same thing as "when the black tank is full". Please educate me...
I would NEVER consider working on the macerator away from home, and there is no need whatever to do so. Also, I would NEVER consider working on the macerator "with the black full" or "with the black TANK full", or "when the black tank is full", and there is no need to ever do that. If it ever fails, I'd just use the 3" hose until the spirit moved me to fix it. Where is the flaw in that plan?
RJW: What is the need to carry a spare that I'd NEVER use on the road? Honestly, I don't get it...
PS If you throw spoons down the toilet, I guess you deserve to fix the macerator. HA! ONLY KIDDING!!!

At this time i do not have a macerator on mine. It seems as if it could be
easy to add the macerator on the very end of the pipe i have now when i want to empty.
Is this a bad idea compared to putting it in permanent? Any scientific experience with
the add to the end design would be appreciated. Thank you Best regards.

Since we are on the subject, I have a Denny Allen complete macerator kit
for sale. It belonged to Jim Brown who had it for a few years but never
installed it. Jim has since passed away and I am helping out his widow
by selling off his assortment of GMC parts that he has accumulated for 30
years. $250 plus shipping for the complete set.

I think the macerator was the best money my beloved PO spent on his coach, dollar for dollar. Dealing with the stinky slinky was the one thing about RVing I wasn't looking forward to, and when he described how the macerator worked, I was sold.
Even better, now that I've moved my bicycle business to Arizona, I got a warehouse / office with enough space (and a big enough door) to park the Royale inside, and there's a bathroom about six feet from the rear bumper. No more dump fees for me, ever.
And FWIW, the PO installed the macerator with slide valves for both the black and gray water tanks, and an emergency 3" port (and even has a brand new, sweet-smelling slinky in the pod). It really doesn't get better than that...

While Corley has a point, let me tell you (from peronal experince) that, if you plan to install a macerator, plan to remove it with the black tank full. .

I also have two valves. At the tank and after the macerator Tee. With the tank valve off, it is not much messier to change than trying to get the 3" washed out and folded back up. That being said, I have not changed one in 40k miles. I have had to give it a turn with a screwdriver when it wouldn't start. Clean the corrosion on the back battery, George!
Macerator is a 2 minute dump with no mess. The only slow time, dumping, is waiting for some poor guy to massage the 3", wash it out, take his gloves off and pull away so I can get in. I don't use the water valve at dump stations because there is nothing to wash.

Despite everything said to the contrary, there is no way I would ever go back to GMC motorhome life without a macerator. Same goes for fuel injection, automatic generator transfer switch, Alcoa wheels, permanent bed with storage, supplemental tank-less water heater and whole house inverter.
