Hey Zack, I think your trucks handles quite well

... where jumping is concerned, as said before by others, the way you land the truck will help to 'reduce' grounding out.
I did notice one or two of your landings helped with good roll out when the rears touched down first, but when you hit all four at once, it was a lot more violent and the truck bounced out of control as a result.
I think it was nitrostarter that said it would be better for you to jump ramp to ramp, and I can see why he said that. looking at the asphalt vids, I can see that the truck will need a little more pre-load on the rears
(and maybe even the fronts with all the squatting during deceleration).
