It's BJ.
I'm an ex-pat from Halifax.
If you're buying a diesel and haven't got a lot of money, I wouldn't recommend a 6.5.
They can be reliable and decent work horses, but it takes a fair bit of cash to get it there. If you do manage to get it to reliably and effectively haul heavy, expect roughly 15-16 mpg
TOPS.
If you're looking for decent mileage, reliability, durability and the ability to work it hard I would recommend (and I can't believe I'm saying this) one of the cummins 12 valve trucks with the P7100 mechanical pump. Stay away from anything with a "53" block in it.
You'll pay a bit more up front, but these are easy half million mile engines before rebuild. They're also super easy to "wick up" if you lean that way.
You just have to deal with the Dodge wrapper it comes in.....
