Advise on truck needed

Hello all, i'm thinking about buying a truck/trl and becoming an owner operator, will be booking the freight myself from the load boards, $60K max
I would like to get either cascadia 2010-2011 detroit-cummins or a volvo 670 cummins is my preferred choice , drove volvo's for quite some time but parts availability and prices scare me
i'm looking at reliability standpoint as well as fuel mileage, manual is my only trans choice 10-13spd, no auto's , will be pulling dry box , need suggestions on which one to get, will buy new and hoping it'll last me long time, utility/grate dane or something else ?
I've been driving for past 15 yrs but have hard time making up my mind
BTW , will buy it in spring time after reg renewals and have very good credit (806) with zero debt ,have 10% down but really like 5%, advice on where to go for credit and % i may get always welcome
All the suggestions are appreciated
Thank you

 

Was talking $60K tractor only(2011), plated dry van trl $25K brand new (utility) , has logistics posts and inflation system , don't need other expensive options
Looks like it'll be a Volvo 670 with cummins , drove cascadia but too noisy inside and i like my cab to be quiet
