The oil bath and drain overflow was your fault (however, I'm sure you know that). And maintenance vs. gas is pretty much a wash given the longer OCI on diesel. About the only expense gas has over diesel is fuel filters which are maybe once a year unless you rack up the miles. And when talking about these trucks and what they cost, if a set of $100 filters once a year is an issue then the person probably shouldn't even be considering buying one. I'm suspecting your experience was also with an older Diesel engine. The newer ones are completely different. No fumes, superb cold weather start up and warming times, easy maintenance, insane power, DEF equipped trucks get great mileage, etc. I can crank my truck and engage the exhaust brake and fast idle and she will be at operating temps and blowing hot air in 5-6 min. And FWIW I get a TRUE mixed avg 17-18.5mpg empty and 11-13 towing with the common determining factors speed, wind, terrain, depending. Sorry your previous experience wasn't to your likings, but if you haven't tried a newer one you may be in for a surprise!
