Hello,
For the years your referring to… The 3208’s are in the front control buses which are lighter and about a foot lower, better fuel economy. With the cat your talking quarts, the Detroit gallons, I’ve had both buses and I’d say that the Detroit equipped buses (pushers) may in some cases have better access for maintenance, other times just a difficult of access but bigger bolts; for most regular scheduled maintenance the front control was about the same in effort as my previous Cummins equipped truck. The pushers are easier to crawl under, just don’t squish yourself. The pushers in general have more subsystems and are therefore more complex, a FC is a great coach to start with, easier learning curve. The 6V’s do have the same cooling system as the 8V’s, which is a real plus for the 6V; you can easily overheat your engine oil on a hill with the 8V, and loose ALL oil pressure when you lift your foot off the accelerator. The cats just go slow and in comparison have a puny cooling system. Detroits use a single weight oil only, and you can use 50 weight if smoke becomes a problem. I suspect that buyers who purchase the bigger bus with the bigger engine w/all the bells and whistles are more prone to replace an engine rather than deal with the possible consequence of being stranded. I drove a 6V PT40 with over 300K miles, kind of moved like a 3208 and smoked, but it could have benifited with 50 weight oil and probably had a few more years of typical RV use in it; a lot of guys would have rebuilt that engine years ago, yet it was still completely usable.
