2012 T370 experience/reviews

Hi All, long time lurker first time poster.

I've been tasked with getting our new spray truck purchased and tooled up. We are going to be doing manhole repairs with it. A lot of guys I know buy a tractor and stretch it and then put the 24' insulated van body on top. The "regular" straight trucks I guess don't have enough power to do the job. I have been told we need 350hp to be happy. 10-12k FA and 40k RA.

We won't be logging a ton of miles on it. The average day would be about a 30-60 minute drive to the jobsite, work all day (truck shut off), drive home. Not a ton of work in the winter so I would be surprised if we put 15,000 miles on it in a year. Another guy I know doing the same work only gets about 10,000 miles per year. I would like to get a truck I can count on for say 10 years worth of work.

I have spent two months now Googling and reading online forums. In some respects, I shoulda just bought a truck blind right outta the gate because now I've heard so many horror stories I don't know which way to turn!!

Currently eyeballing a 2012 T370 with a PX-8, tandems, 28' van body, 10 speed Eaton. 255k miles on it and a rear locker. Coming out of the MHC Kenworth Lease Dept in Kansas City. https://www.mhc.com/trucks/i0342149


The below pic is what the end setup should look like roughly. I know this pic is on dirt, but really 99% of the work is on city streets.
Any recommendations?
