Where is your bath? I have pictures of our Rear Bath Royale two tank mascerator system. The mascerator is between the two tanks with separate long handled valves for each tank.

Side dry bath ( drivers) Jack. I'd love to look at photos. I'm hoping to tackle this in the next couple of weeks.

My '78 Royale side kitchen (driver's side dry bath) has separate black and gray tanks, both with blade valves installed before the macerator. Open the black water valve, run the macerator until empty, close the black valve, open the gray valve, restart the macerator until the gray water tank is empty, and it's done (and the macerator and hose is relatively clean - not "drink out of it clean", but "don't retch if you sniff it clean".
I can't swear that both my waste water tanks are original - my two beloved POs were over-achievers and replaced a LOT of stuff. The macerator is mounted pretty low in the back, using a piece of flexible hose. It also uses an inline self-resetting circuit breaker. The black water valve handle is poking through the chassiis just behind the rear driver's side wheels, and the gray water valve is pointing rearward just in front of the rear bumper, a couple feet in from the left side of the coach.

It would be great to see photos of royale twin tank style macerator set ups if someone has links or photos to post. If you wish you may send to my email. I was going to leave the current set up but realized on our last trip that both gate valves weep and the blade housing is crumbling where the cap to the blades is so I will be replacing everything rear of the tanks. Been reading casually over the years about macerators and being able to pump uphill. Finding a waste dump on the way was kind of a hassle for us on our last trip. If I can pump uphill 8-10' total elevation gain then I can pump into our house clean out. Is that too much to expect??

It'll be a few days before I could get photos of my twin tank system, but if no one comes through, I'll try to remember to snap some photos when I get to my warehouse later this week.
I doubt the macerator would pump 8-10' higher than the tanks. Even if it would, you'd be left with a whole lot of "fun-filled" exhaust hose, which would be "challenging" to walk back to the coach. I guess you could always grab a big bucket, stick the end of the hose in, and walk back down to the coach, draining as you go. Then (it goes without saying), dump and rinse the bucket.

Here is one by Larry

And by Ray Ers.....

A search on the photo site for macerator yields quite a few photo links -- but not always easy to determine the coach set up.

I never thought about that Matt. Good idea I will look into adding an access lower down stream so to speak.

Todd,
Here's the setup I had on my dual-tank X-Birchaven for several years. It's
a rear bath but the principles for two tanks are similar.
http://www.gmcmhphotos.com/photos/g3048-birchaven-macerator.html
While that system worked well, the distance from the gray tank to the
macerator meant that it wasn't easily emptied in some situations. So I
redesigned it with with a separate gray tank macerator mounted near the
tank (it's still valve isolated for emergencies). The two outputs are
tee'd into a single drain hosed. Both of those pumps' control switches are
behind the swing-down tag carrier, as shown in the album. In addition,
there are air bag dump switches for left and right, and a single inflation
compressor (120 vac which can run off of the inverter) which will raise the
ride height from full down to full up in 30 seconds -- useful in many
terrain situations.
