For stand hunting whitetails I'd encourage you to look at the the Limit pack/stand combo. Just got mine and am thrilled with it. Killed a deer second time out with/in it.
Have only had it a few weeks and I can already get up a tree faster and and more quietly than with any other portable rig I've used in 20 years. And the "how to wear a stand and pack at the same time" problem is solved. The size, compartments, and lashings are very well thought out. You could leave the truck for several days, but it's not overkill for an afternoon hunt either.
It's on the Bison Gear website but the pics dont do it justice at all.
