It may be more expensive, but the space savings is well worth it, and $2300 is about $500-$700 more than a separate furnace and water heater, so the cost difference isn't too bad. It is also nice because it can run on electric, LP gas, or both.
I'm just surprised more mainstream makers have not started using it. So far, there have been relatively minor complaints, but I've yet to read about a complete horror story, much less people who would want to chuck the system and go back to two separate appliances.
Disclaimer: I am not affilated with anything mentioned here, but just objectively curious, since it would be nice to see more European/Australian RV advances make it to the US. Another item would be Seitz S4 windows, which are dual-paned, which help with insulation and noise deadening.
