I've got to disagree with most of this.
Yes, diesel cost more to buy.
Diesel, especially the older mechanical injection models are not complicated at all, NO timing, NO fuel mixture none of the hassles involved in petrol engine tune ups. Newer electronically controlled diesels can be an issue for expedition use if there is ever a computer or electronic issue, either due to malfunction or mechanic ineptitude.
Diesel is usually considerably more economical than petrol.
On maintenance the only area that might be more expensive is an oil change. You NEVER need spark plugs, tune ups or all the other stuff needed with a petrol engine.
As for life span, other than the cheapo GM 350 "wannna-be" diesel of the 1970's and early '80's, a diesel should outlast a petrol engine everytime.
Overland diesel is likely easier to find than petrol. All trucks run diesel, no diesel = no commerce. In my travels there have been several times when petrol has been in short supply but diesel has been available.
