For what it is worth (not much), shifting without the clutch on a synchroed box is considerably harder than on an unsynchroed box. Trucks (real trucks) are also easier than cars because diesel engine trannies have much closer gear spacings.

Oh wait, is that a real truck?

That's a real truck, Jack, but it's also a slushbox (Allison 2200 5 speed w/ overdrive and PTO).
It's also an ideal truck to take car shopping for two reasons...
1) You've proven your bling credentials (assuming you don't leave the manufacturer plate on
)
2) Everything you drive will feel incredibly fast, comfortable, and refined.

Did they let you test those, by any chance?

Right now, it varies a great deal depending on the vehicle/transmission. I've driven an 18 speed (you realistically only use 9 or 10 of the possible speeds) and only use the clutch to get started in 1L. When you lift off the throttle, you can pull the shifter out of gear, and just gently push it into the next, and when the RPMs match it slides in. Some trannies (Eaton Super 10s for example) make this nearly impossible, other trannies (most 10s) it's just easier to clutch out of gear and match in, and still others require a double clutch in certain transitions (typically between 4 and 5 on 18s). Downshifting is a bit different, you tend to have to use the clutch most of the time (fortunately you really only have to downshift 2 or 3 times vs 5-9 upshifts).
You're supposed to double clutch all the time but it's too much work.

had one of those in my Navistar-powered International - got to the point I'd just leave the hand throttle (sort of a manual cruise control) on WFO and let 'em grindI
18s boxes, especially when you get the splitter just right

18s boxes, especially when you get the splitter just right I generally prefer the 18s as well. Our control vehicle has a very nice 18 (it's the one I referred to - I never use the clutch on it) paired up to a very nice 550 HP Cat C16.
From an ownership perspective, a proper 10 speed is better - fewer splitters to break, lighter, cheaper - but the 18s pair up better with weeny motors that some fleets like to spec.

Right now, it looks like Jason gave up on boxing his cars up.
