Links to read about Volvo's.  Lot more threads around.  Don't know answers to all your questions, But 2019 and newer have I think it is better valves guides or something like that.  We are all 6'4" here to and have VNL'S and are good for room. Don't know about VNR.  Shorter hood for sure, not sure on inside room. If you want

Miles and maintenance.  The least miles for the money you want to spend and the deal you can run across. Maintenance-- their still trucks.   Paid 25,000 each for 2 of ours and 8000 more for our other one All 2019's. Spent a little more on computer/transmission parameters/idle shutdowns upgrades. 485,000 to 505,000 miles.  Worked good for 1 season. Not 100% sure on ratio, But I think 2.65.  Okay so far, but wasn't muddy last year.  Little lower probably would be better but really hard to find and if you do they probably weren't all highway miles. Probably easier to find lower ratio's on the Mack side.
