It'd be nice if I could pick and choose, but the Peterbilt and Manitex boys have some set deals they like to push, or at least that's the way it seems. A 10 speed Eaton Fuller with the PX-9 380 hp engine seems to be what they are geared up for, pun intended. I'm sure once they get a package figured out it's easier for both of them to stick with it, parts and production wise. I for sure get the impression anyway that if I want to make a change I better be ready to pay extra! The last thing I'll do, should be this week, before sending my deposit off is to ask about "more gears", but I expect to get told this setup is what they have found to be best. Best for who is the question, but I do have to keep the price down as much as possible. The 6 speed Allison auto wasn't even considered, though that sure would be nice in town. About 6 to 7K extra.
My buddy who's buying my Manitex already has one, with a CAT C-13. It has plenty of power pretty much all the time, what I would like to see is what a CAT computer print out like I had done would show for an average fuel burn while the PTO is engaged. Not 1.4 GPH like the little C-7 I'm guessing, more reciprocating mass, friction etc., has to burn more. May be the same going down the road, sometimes loafing a big engine is better then working a small one hard. But, I spend a lot more time in PTO then driving so have to keep that in mind. He doesn't have a CAT dealer anywhere near or else we'd find out. With the specified rear end, they are showing 1600 rpm at 60 mph, I like that better then the 2,000 rpm I now need for 60 MPH. Another thing I need to keep in mind: I charge travel time to get to a job, so do I want to get there at 70 MPH, or 60? If I get there at 70, do I get to charge more per hour because I have a bigger engine? No....I drive 60 now, and will in the future, maybe 65 tops if I'm late getting home or it's getting dark or whatever) it also makes the math real easy 90 miles=1.5 hrs etc. Having half again as much more torque then I do now, even with the same 10 gears, should make a pretty big difference if i keep the crane weight the same.
