Hey,
I have been towing a lot in the m715 recently, and i am not happy with the power of its original engine. If i were to change the engine to a larger engine, what would be the best choice. I have always wanted to have a diesel, but what engine would be the easiest to install, and most reliable. i want to pull a car trailer with the m715 with comfort that I can go over 25mph up the next hill.
