Anyone run a Ram 3500 with 6.4 Hemi?
Looking into a 13,500 lb gvw fifth wheel. It weighs too much for my F250. Does anyone pull anything that heavy with a 6.4? If so, how do you like it? Does it handle the mountains?

Cylinder deactivation on the 6.4 Hemi when used in Ram's Class 4 and 5 trucks is only used for PTO operation. They do not deactivate while driving. If you drive a Class 2 or 3 always loaded, you will rarely see it deactivate cylinders.
Mine was in 4 cylinder mode a lot today with no trailer. I went 500 miles.
