As a senior citizen I vote for oil as easiest!! I've hostled a couple oil burners by myself and it's not difficult, be a little tougher with coal though a
decent bed would allow some minutes without too much effort. Earl would be the guy to answer this, he's done a lot of both. I rode the 3 around
the yard up on the SVRR for a few minutes without the firebox being touched though it'd be a challenge up hill. I wonder at keeping an organized
fire on a wood burner would a number of people don't seem to have a problem with, splitting the stuff and getting the length right would be a pain!
