Question for LxMan1
It's not like him to not answer on here

As far as maintenance goes both engines are very good and they are both almost identical to work on.
From what I've seen they both get close to the same mileage too so if I was towing at all I would go for the one with more power. Towing with a small engine or driving in hilly country where you make the engine work harder will kill the mileage on a smaller engine as you will always be more into the throttle.
More power might not always be neccessary now but in the future you might decide to tow a heavier trailer or whatever and you might wish you went with the bigger engine.
That's just my $.02 worth
