Leo,
You're starting to scare me
Seriously, I got a tour of an apartment on wheels that the owners had an espresso machine and one of them $700 pod coffee machines - they felt if they were going to live on the road in such rough conditions, then some sort of civility is needed in their little 110" apartment on wheels. Those million dollar RVing expediters, got to love them.
I am wondering why are people go through so many? Is the heating element getting cracked by the vibration?
