I find it VERY handy to separate the "nasty" galley water from the clean shower water when camping in national forests. I'd never dump garbage water on the ground but when it's nothing but shower water there is nothing but benefit from dumping it. You are right though about camping with a sewer connection. On those RARE occasions when we do that I just leave the galley water valve closed and dump it before we leave rather than as it is accumulated.

We had the same problem with our old camper, same unit as skipnchar. I wound up buying the Y fitting and hooking up 2 hoses but it is still a pain to crawl under the slide and dump the rear tank. They do make extension kits for the handle to make it reachable.

I would worry about connecting them permanantly. Some of these thoughts are based on if you permanantly crossconnect the tanks. If you were boondocking for a few days and the tanks were at say 3/4, then you hit an uphill climb you would send a water slug into the back tank that would overfill and possibly damage it depending on the design of your crossconnect. Plus you open yourself up to an extra path to be clogged. Even if you install valves in the crossconnected portion it would only take once to forget to close and then your in trouble. Also if they were connected it could affect your weight distribution if the water could flow back and forth.

Just a few things to think about.

I wish I had a photo of my setup. It works well, but I do have to watch what goes down the drain --no chunks please.

one of these

and one of these

Sorry for the links to commercial sites. It's the best I could do with dinner on the stove and no pics in my library.

It may sound dumb but I use one of those things that people use to pick up items off the floor or off a tall shelf to open and shut my drain valves which are under the trailer slides. I used to crawl under the slides to operate the drain valves but no more!!

Do you have enough drop from the rear tank to the dump valve to run a 1 1/2 pipe from the back tank to the 3" pipe at the dump valve? and miss the axle movement?
Ours has a rear galley tank that has a seperate valve.. then the 1 1/2 pipe runs from the tank to a couple feet in front of the front tire.. there is a "y" with one being 3" the other being the 1 1/2... this goes to the back of the dump valve....
Hope all of this makes sense... end result is I have 3 tanks.. with one dump valve/connection
