Clifford says his propane boiler takes far less fuel than a diesel boiler to produce the same amount of heat.  Considering physics, how is this possible?  Diesel has more BTUs per gallon than propane.  Are diesel boilers that inefficient?

It may be a moot point as I can't find anyone selling a propane boiler for an RV.  The Primus system seems to be mostly sold in Europe.

The modern gas systems are running exhaust temps so low that they can be connected to the plastic drain vent pipes in houses. This low temp means that more BTUs are going into the medium to be heated be it water or air therefore higher efficiency. Diesel systems can't match this because they must keep the exhaust temp high enough to keep the particulate matter from sticking to the exhaust surface which would plug the exhaust in short order.

In my experience with oil-fired boilers, the exhaust temp. was kept above 240 degrees F because of water condensation. Not that water is bad, but sulfur and water are. It seems that with ULSD exaust temps could go down on a diesel fired unit (& efficeincy would go up).

Nick - Not piling on - but now is the time you need to avail yourself of some "family" counseling - remember it wasn't 'if' but 'when' you would need it - just part of the transition - don't get weak - hopefully she's just testing you - if you were in her shoes you'd probably want to know who's on your side - we all know YOU ARE - just make sure SHE KNOWS - Got my fingers crossed and my money is on you - Pulling for you and yours -
