Thanx to you both for taking the time to reply. I had seen the slide problem in some other posts and understood it was a "full Wall" issue. I appreciate the info and clarifications!
I am much less concerned about the Cummins, as I have had several, just not the ISB. My experience is with Sparatan and I except Freightliner to be just as good!
Thanx again for your help.
