I didn't realize the 6.0 was offered with an electric motor. Mine has the 6.0 engine, and yes it needs to be monitored and yes the 05-07 has a few more issues than the 03-04. Being that it has 100k, one would suspect the mandatory upgrades should be fixed already, check your vehicle via oasis report at the dealer. Not everyone is a bad truck. My 03 has 116k on it and my oasis reports shows a trans and egr replaced at 54k. Back on topic, I bought a slider for mine and didn't end up needing it due to an extended pinbox on my 01 5th. However if I change campers or have to move another 5er it may come in handy. And please keep your personal chimes to yourself if you are not posting relevant info to the OP's questions, thanks. You'll appreciate the request when you have a question you need answered and people chime in with useless rants.
