Shifting the NV5600: how to?

[slowneasy]

I need some advise, opinions etc on shifting the NV5600 better than I am now with a loaded trailer that weighs about 13K. That's not much weight compared to some of you guys but that's about all the weight I want in my driving situations. I live in the northern part of LA County and my biggest problems with my shifting is on the surface streets/roads that have stop lights and up/down grades. It wouldn't be a problem if the lights weren't there to screw ya up but they are.
Upshifting- how long do you hold the current gear before shifting (RPM's)? And once you shift into the next higher gear, and with the clutch still in, do you increase the rpm's and if so, by how much? One of my many problems is that on shifting, if I don't increase rpm's when the clutch is in, I lose too much monemtum. But a lot of times if I increase rpm's, then let the clutch out, I get some jerking of the truck/trailer. (Not exceptable as trailer is a horse trailer).

Downshifting is not as problematic for me but obviously, still needs work. I'm sure if my upshifting improved, downshifting would follow. Another slight problem is that this truck isn't a daily driver so even though driving it empty I have no problems, it's not like I can practice with the trailer regularly to figure it all out on my own.

Thanks!
