some beginner manual starting issues

Never start out under power. Let the clutch out with no power to get the truck rolling then apply power. Your drive line will thank you after awhile.

 

I agree with the last two posters. Start in lower gear like 2nd. Trucks nowadays are fuel injected and if your In the right gear to take off it won't buck, the fuel injection is all you need, you shouldn't even have to push down on the accelerator unless your on a incline. Your instructor is obviously impatient and doesn't want to give you the chance to work up through the gears and down. I would go above his head and ask someone, cause if your at gross your gonna have to start from 1st sometime, why not get what your paying for and get some extra practice.

 

i await the snapping sound of the drive shaft, someday...will the instructor be around then to say he was wrong.>???

 

Way to go see what a little seat time gets you.
I am with the others on starting in 2nd gear. Does the truck have that beep beep alarm when you back up? It should and if so that is how you can tell if not in 2nd gear.

I believe we are talking about the same gear. A 10 speed 3rd is the same as a 13 or 18 2nd, position-wise. Look at the shift pattern on the knob or the dash

 

I'm going to be the voice of dissent here, but I start out in 4th on a regular basis. If I'm loaded up really heavy I'll go down a gear or two. Empty, no, it's 4th gear.

One thing to note, too, is that all the trucks I've driven, being local here in California, are geared for California, which is to say a little lower. Still I doubt that my 4th is equivalent to most 2nd in most trucks, maybe closer to third, but not second.

 

I would be willing to bet your clutch is getting hammered whether it jumps and shudders or not
