I see thar Jack has concerns about the SUMB gearbox. He need not worry.
We have sold about 200 SUMBs now and have *never* had a request for a
replacement gearbox.. It is built like the proverbial brick edifice and I
cannot imagine bursting one. We have plenty at very low prices.

without power steering. A soft ride compared to most large troop carriers.
The French made it a comfortable cab too, like someone just reported, a tilt
out windscreen, roll up windows, heater, spring seats, handy rifle
placement... quite nice all in all.

> The suspension is coil spring too and set very high. When pulling
yourself into the cab the whole truck will tilt a good deal, which is a
little disconcerting. The reduction gear suspension, while excellent for
clearance was never designed to run at 60 mph, while no doubt the engine (a
flat head ford type of the 1953 vintage) would do it, the reduciton gear
design is unstable at high speed without a massive steering dampner. Many
troops have experience that high speed wobble and it can be quite dangerous.
50-53 mph is typical max speed due to wobble.

carb does remarkably well. Would be even better if it had a modern
electronic ignition, but if you are into dual points, this is a good enough
system.

> Tires are NATO treads, forget the size, but they were fat compared to
ND's, good traction, although prone to some side slippage in steep going.
An odd feature is the air intake is located inside the cab, presumably for
drawing less dust.

> The brakes are very good, air over hydraulic and they spit air about 20
seconds. Which is loud and unnerving. I am always listening to sounds of
possible trouble while driving and spitting overpressured air out always
bothered me.

pattern, but I don't know what you would do if you had to replace one from
the US. Shipping would be horrendous.

> Price wise, the French government dumped hundreds, if not thousands of
these trucks about two years ago for an average of about $800-$1000. Those
same trucks were selling in the UK for about $2500-2800. Now in the US
folks are asking about $6000 plus. Not sure they are worth it, unless you
just have to have it. Especially considering recent prices in Europe. They
are a nice truck, very solid and in my humble opinion "butt ugly."
