Thetford Style II in a boondocking setup: worth changing from the stock toilet?

[isabellathomas]

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.
