toilets need to be on their own dedicated circuit shared by nothing else with a separate breaker...so if you're "upgrading" from manual to electric you'd have that additional expense. And you should know that all Jabsco products are now made in Mexico
and components made in China
and other comparable "offshore" sources. Raritan products are still made in the US. If you want an electric toilet, you can buy a Raritan SeaEra "conversion" SeaEra Conversion Kit
which allows you re-use your Jabsco bowl seat and lid (yes it WILL fit) for about the same price
as the Jabsco at WM. Ask HopCar for a quote. You'd have the same additional cost of the new wiring
for it or any other electric toilet.
