Best RV toilet

I had the Thetford Aqua-Magic Style II ( Side Foot Flush) that had a similar problem. I investigated both repair and replacement. Replacement won out. I selected Thetford Aqua Magic Style Plus (Front Foot Flush) for primarily for the ease of replacement from what was available. The difference that I watched was the water connection. In my case the water line came through the floor offset a little and the Style Plus required a little more offset but I had the slack below the floor.
We like the new toilet, I would never install a Hand flush.
