Reak Kitchen tanks dump fix
I have had two rear Kitchens & both had a rear dump for kitchen gray. Means lots of slinkys and moving at dump stations to dump all tanks. I did a fix on this one. Parts: (1) 3"x2" Y / (1) 2"to1....

What you did is OK however I would have used a mechanical coupling on "no hub" coupling to transition from ABS to PVC. I never trust the various transition glues, the joints all seem to eventually loosen and leak. The mechanical joint will not fail. Rolling up the 45º to create more fall isn't quite kosher either, but in your RV application I guess it maybe OK.
Rolling the pipe creates a trapped section of pipe that will always hold water and potentially collect debris and create a clog.
In your RV application you maybe able to get away with it because the RV is moving enough that holding water may not matter.
I like the idea, hopefully it works out for you.
No hub coupling
Please explain how I use this coupling to connect 1.5" ABS to 3" ABS with out fittings and adapters or PVC as the are dimensionally identical. I have used that fitting for coupling or splices before, but it was same size to same size not up size or down sizing. I may have one in my shop now. Diagram?
Lets start with they make a 3"x 11/2" no hub coupling but that really not what your trying to do.
My point is instead of connecting ABS directly to PVC via transition glues use a no hub coupling in between the to different type of pipes so that you connect PVC to one side of coupling and ABS to the other side of coupling. The coupling will be the same diameter as the pipe you are using.
