Fixrim,
Your are unable to lock up the rear end like your truck, but the Prevost has good traction when you lift the tag, just make sure you are on stable ground or it will sink.
You will find that your truck will do some things like pull a trailer much better than a bus, a lot due to the radiator in the front and not on the side. Also the 6 speed allison and the final rear gear ratio just is not the same as most over the road trucks. Having said all that, nothing goes down the road as nice as a Prevost!
