Rear Axle Ratio 43:10
5 speed gear box
After a quick look around the EPC this truck is setup pretty much like ours. Same axle ratio, gearbox and engine. It looks like it has a PTO also. With the larger tires we cruise at 55mph at 2300rpm. There is 1 faster axle but not sure how common they were, you can always change the ring and pinion out (parts start at about $5k). The OM366LA can be upgraded to 280hp with an injector pump/injector change (about another $5k). So far we have taken a wait and see approach on both of the upgrades. With steep hills we do slow down from 55mph, but so far not lower than 4th gear. I am sure we will slow down more with steeper inclines as we have only been on the east coast of the USA.
If you want PM me a link to the truck and I can take a look and see if anything jumps out. I have to say, so far we really like our LN2 and have no regrets (though I do wish it had an over drive gear for I95 and to get the revs down even at 55). If you decide to purchase, and I am assuming the truck is in Europe I can recommend a really good shipping agent, he was the best price and extremely good at keeping us up to date. As a matter of fact he will likely handle our shipping of new parabolic rear leaf springs.
Joe is correct with the VIN, ours comes up as a passenger car also. A bit confusing with insurance and part counters (which I have given up on in the USA).
