one disadvantage would be the lack of RPM. the gas engines turn more RPM.

An awesome thing about diesels is the massive torque they make, generally more than a big block gas engine even. But, they can't rev up nearly as fast as a gas engine, so it's harder to get the wheel speed you need in the mud sometimes. Another really cool thing about diesels is that if you have to submerge the engine in the water, you don't have to worry about an ignition system getting wet and not firing since there isn't one on a diesel, but generally with some time and silicone, you can get a gasoline engine to run ok underwater (assuming they both have snorkels on them).

Diesels generally get better MPG than gasoline, but are a bit louder and the exhaust gasses aren't quite as clean as a gasoline engine. Another possible downside to diesels is that if you head out to some more remote places, availability of diesel fuel can be a problem.

Since you're in the mud forum, I'm assuming you want it for mud runnin'. Is there anything else you'd want to do with this truck? Maybe tow a trailer or just curise around town, etc...???

Diesels make a poor choice for playing in mud. They're heavy & won't spin the tires like gas engines. But, there are instances where they are useful. Mileage & towing ability come to mind, but you have to be cautious. Those turbos get hot & you need to let the engine run for a while when you stop to let them cool down (ever notice how the big rigs are always idling at the truck stops?). This makes them somewhat of a poor choice for daily driving & short trips. Also, it takes something like 120-150,000 miles of increased fuel mileage to pay off the additional up-front cost of a diesel (if buying new). If your truck isn't driven 20-30,000 miles a year, you could be costing yourself more than you save. Just some stuff to consider.
