I've never driven a Mack road truck so I couldn't say much about them. The only Macks I drove was in a quarry hauling crushed stone for the asphalt plant when I was 18. I think I have some old pics around here somewhere........

I can help out with specs, make rpm/mph charts, etc..

Nowadays the wrong specs can cost you 20k a year, easy.

Something as simple as a direct drive vs overdrive, the direct drive tranny can save you 2k a year!

If I was buying a new truck, it would have 2.64 gears, super singles OR XDA "energy" low pro 22.5's, a 10 speed direct drive ultrashift, or maybe volvos I-shift if I was going with a volvo engine.

I talked to a guy running that combo, 12 speed volvo direct drive tranny, and a 485 D13, he said he was getting 7.5 mpg at 60 mph. Almost unheard of with a new 2008 truck!

Anyone that buys a non-aero truck nowadays is nuts.

.... a CPA stated (on this board?) that 72% of owner-operators (probably including motor carriers too) didn't know what they were doing.

If you INCLUDE spec-ing it'll probably raise this to 90%. :sad:

I read of 2.73 rear-end gearing, BUT 2.64? Who manufactures 2.64's?

What do you think about all these aerodynamic items they're experimenting with (walmart, et al - trailer skirts, baby moons, cab extenders, front bumper air dams etc.)?

There's tons of trucks on truckpaper with 2.64's. Every single schneider truck has them. Good gear with 22.5 LP's if you want to run 60-65.

Actually I have some products on my truck. I'll get pictures later, as they're not fully installed. Will reduce trailer gap about 8" at the bottom, and 12" at the top.

Trying to convince my company(99% o/o) to put side skirts on the trailer.
