Personally, I've always thought the 2-stroke Detroit Diesel sound was "cool", but then again I've not driven a vehicle with one of those engines for any length of time, so it may very well become tiresome.
He doesn't post much anymore but forum member VXclimber180 posted some youtube videos of his Detroit 4-53 equipped Tucker 2742. Here's a link:

This may give you an idea of the noise Don mentions.
Here's another video of the Tucker:

Incidentally, Tucker lists the unladen weight of a 1700 series as 8,410-8,630 lbs; depending on options. But that's for the standard models not the ones with extra-wide, extra-long cabs. The wide track models (such as VXclimber180's machine) weigh in at 9,290-9,510 lbs.
Just a thought-----There's another forum member who has one of these extra big Tuckers. (I can't remember his screen name, but IIRC he's in the Cooke City, MT area.) I think he bought the machine from Snotrans. Perhaps they could put you in touch with that fellow and you could get his thoughts?
