I pulled 26000# behind our 94 for over 200,000 miles. Initially had some over heating problems on long grades. Corrected the problem with installation of a slightly larger radiator and the learning curve of properly maintaining rpm's and shifting. This may not relate to a 1990 as ours has a Series 60 and the trailer is full air.

Thanks for the info. I would have preferred the 60 series as well, but for the most part the coaches with 60 series or Cat are out of our price range.  We have the 60's in our farm trucks.This is only a 4 sp.  Salesman told me a 6 but not so.  This will be used in Western US and Canada for the most part so I want to get it right.

Trailer has electric/hyd disc brakes.

I understand the Newell doesnt use hyd levelling, rather depending on the air suspension. Is that correct?
Thanks for the replys
