I was at an RV show over the weekend and noticed that a lot of the new units had two holding tank outlets.
The setup looked like the bathroom was on one outlet, with the usual black and gray dump valves. The second outlet was for the galley sink, which due to its location was best suited to having a separate holding tank.
My question is to people who have a trailer with two outlets is how you normally handle things at the dump station. One long hose that allows you to drain one at a time, or do you pull forward a little more and aggravate the person next in line that thought you were done.
I'd also like to know how you connect things up when you have a site with the usual single sewer connection. Did you have to build a wye configuration of sewer hoses?

We have three dump valves. Our galley has its own 40 gallon gray water holding tank in the middle of the trailer. At the back we've got two more 40 gallon holding tanks, one for the black and one for the gray (shower).
When we're dumping, we center the dump inlet between our trailer's two dump outlets and use a 20' hose for dumping and flushing.
When we're at a site with full hookups, we usually just get one set of hoses out and move them around as needed. I don't use a "Y" connection.
We've never run into a problem about anyone getting upset about the time it takes to dump. Overall everyone understands the time involved.
If we're going to do a very extensive dumping and flushing, and we don't have full hookups at our site, we wait until we arrive back at our storage facility to dump. We can then take our time and flush the tanks as many times as needed.
"Hi! Great day, isn't it? Just so you know, when I'm finished with the front tank, I'll be pulling up to dump the others. Just thought you'd want to know. Have a great day!"
Just leave the hose on the ground when pulling ahead and the fellow behind you will know that you're not finished. Or will run up to let you know you forgot your hose. THEN you get to say, "It's a great day!"
