Apologies if this topic has been done to death but I was hoping to get opinions on gas vs diesel on a 350/3500 series truck. I am in the market to lease a newer truck... the truck will be used for snow plowing / salting in the winter and irrigation in the summer. Max it would have to pull is 5000 lbs. I have never plowed with a gas truck. I currently have three trucks in my fleet that are diesel. - 2005 F250 sick.0 superduty - 2016 Ram 3500 Cummins - 2014 F350 6.7 L diesel. I find that the issues I have with the newer diesels all result from the exhaust system (sensors malfunctioning, DEF heaters breaking down) Oddly enough the sick.0 F250 runs well but it's being replaced due to rust.
