You have an option of Detroit Diesel DD13 or DD15, or the Cummins ISX12 or ISX15.
For tractor-trailers, it'll be either the 12 liter ISX12 or the 14.9 liter ISX15.
That would actually be dependent on the make and model of the truck, not the engine. Even if it was dependent on the engine, you never specified if it was the ISX12 or ISX15.

an n-14 cummins weighs 2770lb dry and 2890lb wet. dry meaning no coolant ,engine oil,or fuel
Roughly 1200 pounds.
About 440lbs from what I've read.
Without knowing the year, which Cummins engine (e.g., N14, ISX12, Family 1 ISX15, Family 2 ISX15, Signature series, etc.), and what the gear ratio is, I don't really think much of it, either way. If I were to speculate, I'd guess you're looking at a fleet truck. Without knowing which fleet, I can't comment on how well it was kept up. If it was a Swift truck, you'd be looking at an ISX15 at 400 horsepower with 3.36 rears... which will put you in the "sweet spot" for that engine at around 67 MPH, but not nearly enough power for me, personally... nor would anything else with a 10 speed, as the highest torque rating available for a 10 speed is 1700.
