Maybe, as Gas seems to be the nomal. However, I initially thought, having long experience in sailboat cruising, where gas is a very definite explosion possibility, that diesel was a safer option. In practice over four seasons canal experience, I have found the diesel option has had very definite advantages, and for me, no drawbacks at all. The central heating option alone has been fantastic, cheap and extremely comforting to have the whole interior warm, rather than going into a cold bedroom.
As in all things, opinions differ, and discussion is a great option.
