Hi smlranger,

I didn't realize they were that expensive? But I for one would gladly pay the difference to only deal with one black tank.

Gravity toilets cost about $300, are more reliable, use no electricity, and use about 1/3 of the water per flush.

Alex (Trebek), I'll take simplicity for $300.

$300? That would be a throne.

It isn't just on MH's, I've had a fiver and a TT that had the same problem.. The simple fix was attaching a dump station ( for lack of a more simple term ) that had an opening on each side that I could attach the black line and the other side for the gray water and then a hose from the " T " to the dump tank. It worked out okay but you're right , why not two lines meeting in the middle with the lift valve for each to dump.

There are gravity, vacuum assisted flush and macerator toilets. When the toilet is not placed in close proximity to the black tank it is common to need assistance to gravity to reach the tank. The "assistance" aspect is pricey but the demand for two toilets is definitely there in the marketplace.

Ours has two black tanks, with both toilets being porcelain gravity toilets. I like it this way as it almost doubles our holding capacity, and uses much less water. I don't always empty the rear tank but when we have to dump both it literally only takes at most an extra 5 minutes. For those who have never seen them on a MH they are actually pretty common. I also prefer the "simple" system as one less thing to worry about while traveling.

I'm glad I only have one dump station. That's enough for me to have to take care of.

Or, or you have been missing that extra tank all these years and you are full of you know what.
Even with two dumps, although not the most pleasant job, no big deal. Of course, I am a licensed plumber so nothing bothers me anymore.
