I ditched a diesel for gas and don’t miss the diesel yet. Emissions and other diesel specific issues were mounting. I towed nearly 6,000 miles so far, including through Colorado with a 22’ travel trailer and didn’t notice any real deficits to having a gasser. Lower mileage is offset by lower gas costs, and towing power at altitude has been just fine. I was worried about losing the diesel power but am very pleasantly surprised. Unless you tow super heavy nearly all the time, I would say a gas truck is a better choice.
