Best RV Toilet?

I'm replacing the toilet in our 86 Limited. Bathroom room is a premium. I thought I wanted a Thetford Aqua Magic V as it has outside dimensions similar to the old Thetford that's in there not. The old one has developed a leak in the flush valve.

I was shocked to learn the new Thetford toilet does not have a "down pipe" from the bowl to the floor. The water just spills into the lower chamber of the toilet and a "gravity" directs the water to the black tank. The whole lower chamber of the toilet is "dirty". I can't imagine I would want one of those. I understand it is sealed, but removal would be a mess.

My new Dometic 310 in my Trade Wind has a molded in down pipe as I would expect. The Dometic is too big for my 86 Limited. No room for that big, oval shaped bowl and seat.

So, like tow vehicles and hitches, I figured I'd start a "toilet review" thread and see what you experts have found for good replacement toilet. I want a good design. Too bad Toto doesn't make an RV toilet.

Personally I think the best head for trailers would be a quality composting unit.

Keep the discussion coming. My toilet works, an Aquamagic V I believe but it is like a child's toilet to me- prefer a residential elongated. Not a huge issue but the throne is a bit small! Still,it is better than a bucket and a walmart bag!

I'm not ready for a composting toilet. Reminds me of my cat's litter box.

The "residential" style toilets are too big for the space I have. Airstream designed this bathroom very efficiently. They probably picked the shower pan and toilet and designed the room around it. That is what I did in my Trade Wind.

The Dometic 310 I have in my Trade Wind wasn't all that impressively built. The plastic connection male nipple had a 1/4" long un-threaded extension on it. I suppose it reached down to the rubber seal on some type of toilet swivel connectors. But the flex connector I had did not allow room for that long extension. I had to mess around too long to get the thing connected. Plastic threads never impressed me. And the flange seal wasn't just the best design I have seen either. Further, the bowl is big, but it is shallow. I don't know how well it flushes yet.

The Thetford Aqua Magic V is the right size. But the plastic flush valve and mechanism sits high in the back of the toilet. And this design with no down pipe just bothers me. I can't imagine. It's like having two black tanks, one above the floor as part of the toilet, and one under the floor. The old Thetford had the slide valve down at floor level. There was almost 6" of down pipe molded right into the bowl.

So I was just wondering what other Airstreamers have found that seems well built and functions good.

Wouldn't give 2 cents for the Dometic 310 High Profile toilet that came with our 2012 AS. The toilet leaks at the seam between the bowl and base. There is no way to repair this. Took the toilet out and you can hear the water that has accumulated in the pedestal. We are currently looking for a replacement but I guarantee I will not buy a Dometic.

I think if you were really boondocking the composting would be the way to go. Having a wet bath, not really an appealing option though (apparently has been done). Would consider the urine/waste separator units though and the solar full time fan connection manditory.

Resale value you'll likely have to return to original config before you sell though.
