My analysis from when I was debating buying a deuce and a half back in '06:
Deuce Good/Bad:
Good:
- Extreme coolness factor. Ownership means automatic invitation to any and all parades within a 50 mile radius (slight exaggeration but not much)
- Extremely simple to work on
- Fairly competent on the trails (e.g. Tellico 5 ton dumps trucks)
- Can literally tow a house (the 10 ton versions do exactly that - look at the ads for the Kennedy House Moving Company), although max rated is 10k lbs or so.
- Parts are fairly plentiful and there's a good technical support network (Steel Soldiers.com)
- Designed to run on almost any type of fuel: diesel, veggie oil, JP-8, av gas, commercial gasoline, biodiesel, etc. I think the max gas ratio is about 50% or so.
Bad:
- Very loud; ear plugs + muffs usually required for highway driving
- Very cold or very hot depending on the weather (like reptiles, they take on the external temps)
- Requires very large tools to work on (10 ton floor jacks, 1" sockets etc.)
- Very heavy parts and equipment; GVW empty is around 13,500 lbs. vs. 8000 for our PSD's; stock wheels and tires weigh +200 lbs, Super Singles typically weigh in the +300 lb. area.
- Slow; typical highway max speed is 55 mph; this can be slightly increased by going to Super Singles with their larger diameter tire plus upping the boost a little
Deuces show up on egay all the time for $2500-$8K all the time. There's a reason for it.
