Our class C still has the original toilet, and with the amount of dry camping we do here in American Samoa the water use per flush has started to bother me. I keep coming back to the Thetford 42058 Aqua-Magic Style II as a possible swap, and I found this comparison online: Thetford 42058 Aqua-Magic Style II RV Toilet Review. It sounds like the foot pedal and lower water use could suit how we camp, but I'm not sure about the rough-in dimensions matching our current flange or whether the plastic seat holds up over time. We're also on a tight budget, so I don't want to buy something that ends up being a sideways move from what we already have. Has anyone here actually swapped one of these into an older class C, and did the install and long-term durability work out? Any thoughts on whether it's a real improvement for boondocking would help.

We have basically the same toilet you’re looking at possibly changing too. The only water we use is what’s in the toilet bowl to helps the seal and stay soft no foul odors. Ours drops directly into the black tank so we don’t need a water push if yours is the same it’s the way to go.
