Thanks, Bob. The plan is for something like this:
The "inspirational" truck is a 1974 W924L with a Detroit Diesel 12V71. I'm going to stick with the Caterpiller 3408, though.
As for the kit, it's not bad. I like it so far. The fit of some of the engine components is poor, the air bags on the suspension & the air tanks have hollow backs, and the cab/hood/sleeper is molded in the dreaded red plastic. The fit of the frame was good, and the chrome on my kit was good. All in all, it's been a nice build. This is my first Revell of Germany kit, so it's been a learning process from the usual AMT kits. I think the other in my stash will be a nice doner for a W900B.
