I really need some help here. I've been looking at pic related, but I can't decide if a hammock is a good choice or if I should try something else.

I'm 6'2" and about 240 pounds. I'll mostly be in 20 degree and up weather, but I'm trying to keep space and weight down (not ultralight though, just reasonable.) Kentucky bro, if it helps.

Would I be smart to get a tent with a vestibule for pack/boots/cooking/etc? Is a hammock system more versatile? Would a bivy give me enough room for anything but my body?

Love hammocks, mostly experienced with tents, never tried a bivy.
