Uh? 3208 should not be uttered in the same sentence as Cummins 5.9 or Duramax. 3208 is a good reliable engine that was put in everything. Parts a readily available and they are easy to work on. They were produced as a "throw away motor" though. They don't have very good rings and are prone to smoking badly especially if they arn't worked very hard. I have 2 10 yd dump trucks w/3208's that have plenty of power. I have a buddy w/ a 50' charter boat w/twin 3208's and that bitch screams. I guess what I'm saying is it's not a bad engine but it's no Dmax.
This makes no sense...
It is an auto(Allison). Will it really be a pig?8k hell thats nothing! Our service truck weighs 30k and does just fine. The only issue will be tranny. 9 or 10sp would be best. Auto will be a pig.
A 3208 is no 3406 but a 3406 in a motorhome is like a LS1 in a Pinto. Cool but way over the top.
I love the allison in my d-max but every heavyduty truck I've driven w/ a allison is a slow slug. Sorry, it might be fine but my experience hasn't been great. A 9sp swap would be a pain in a MH but would be cool to drive. Can you test drive it?
