New time class A tank questions

I DON'T SEE ANY ADVANTAGE TO 1 TANK AM I MISSING SOMETHING? $18K SEEMS A LITTLE HIGH PRICED. WOULD HAVE TO BE IN MINT CONDITION AND EXACTLY THE LAY OUT YOU ARE LOOKING FOR. :?

I ALSO DON'T SEE THE ADVANTAGE OF JUST ONE TANK. $18 K SEEMS A BIT HIGH. WOULD HAVE TO BE IN MINT CONDITION WITH ALL MAINTENANCE RECORDS.:B

Thanks for that link. I posted to that topic. Hopefully, the OP will return to the original thread.

The OP already has a long thread running on this same issue over in "Beginning RVing".

Trust me..you don't want to combine grey and black tanks. If for no other reason than the flushing the stinky slinky get when grey follows black. In most MHs the coach is "built" around the tanks

I agree--one tank doesn't really make sense. Having the bathroom sink plumbed to the black tank does. Our previous rig, a Triple E Commander, did. This one doesn't. I fail to understand why so many manufacturers install black and grey tanks of equal or nearly so capacity.

If boondocking for any length of time we put a plastic dishpan in the galley sink and dump the dishwater down the toilet.

In at least some RVs, the tanks are put in before the floor is laid, and cannot readily be removed and replaced without removing the floor. I have no idea if this unit is built in that way or not. I would not expect it to be a simple straightforward job regardless. At any rate, you could get a better answer than most of us could possibly provide by examining the unit and seeing how the tanks are mounted and/or enclosed underneath.

I'm also unclear on why you'd want a single holding tank. You won't gain a significant amount of capacity. It would be a lot easier and simpler and less expensive to install a pump to transfer gray water to the black water tank if you need to equalize them. (Even if the only gray water you use is for handwashing after using the toilet, I doubt you'd be too likely to fill up the black water tank long before the gray water unless the bathroom sink is plumbed to the blackwater tank—which is sometimes done.)

X-2... That would be a deal ender for me on any RV with a combined tank!! You eliminate a couple of important aspects of separate tanks.

Why replace them and why one tank?

good question. I've read other posts in the past about wanting to do this and am at a loss as to why.

Why replace them and why one tank?
