No, not really. Coach and E450 were great. Used the tow/haul a lot in the mountains. It really helped. Still not sure about the inverter operation but did not have any problems. We packed to much was one thing. Need to watch that in the future.
When you pick up your new rig, you need to have the dealer SHOW you how to operate every system. Not just talk their way through it. A mistake I made.
Any other questions, let me know.
