In general, I love propane. It's great stuff.
Unfortunately, motorhomes have the propane tank permanently mounted. That is very annoying, because it makes filling it much less convenient (drive the camper wherever), and because if there's a problem with the tank, it's much harder to replace.
Also I don't understand trusting gas in your house but not your camper. The camper is less well sealed than your house, so any leak is more likely to escape the camper.
