Thoughts on 2005/2006 Cummins ISM 500/ Allison 4000?

My wife and I are seriously considering the purchase of a nice used 2006 Newmar Essex pusher with very low millage. I’m not familiar with the Cummins ISM but living in Colorado I really want a combi...

Pull an oil sample and send it to Blackstone labs, do the trans as well. That will tell you (for 50 bucks) if you are looking at mechanical issues.

if I won the lottery (doubtful), I'd order a Prevost with a 500 horse DDEC and a 6 speed Allison with retarder. Go big or stay home.

Wishful thinking on my part...lol
