Funny, would have pictured you as being the double clutch kind of guy. Not a bad thing, just would have thought.

Floating/sliding whatever you call it, does take some practice, you'll grind less and less and one day you'll notice you haven't ground the gears all day.

yup and when I do start to grind 'em again I know its time to go to bed.

I just got off the road and I start with Performance Food Group tomorrow, it's a local gig. I've been driving a freightliner and I can slip gears in my sleep...now I'm going to an International daycab so I'm wondering will the shifting be about the same? Will it be easy to adjust to and float like a freightliner?

I learned how to "float gears" and you can too!
 
Well,
I learned how to shift without the clutch today. I had been trying to understand how it worked and why I could not ever do it before but, when my trainer said, "Don't be afraid of getting into the engine and put a little press on the shifter in the direction you want to shift as you let off the gas." After he told me that I tried it and what do ya know it freaking worked.

I went from a cabover to a conventional, and I was really worried about this. Cable shift to a direct shaft right into the tranny is a big difference, but it's all basically the same. I think you'll find the bigger difference is going from a Cummins (all hail Cummins) to a Cat to a Detroit or whatever.

Correct me if I'm wrong but i think it goes

Cat = Quickest at dropping RPMS
Cummins = little slower
Detroit = slowest.

This is why different trucks(motors really) seem difficult at first. Motors are quicker then others when it comes to dropping the RPM'S to match the road speed.

My limited experience tells me cat's tend to be quite lazy and quite easy to float. Cummins require pretty good timing. I've only driven a detroit a couple two-three times... as I recall, the one I drove wasn't much different than cummins as far as timing goes. Maybe a smidge slower.
