OK I want to list what I tell evey oogle before they step away from society. First and most important, a great sleeping bag. Don't go to Walmart. You'll be trying to replace the damn thing monthly. I use the Military 3 price modular sleep system or "Bivvy" make sure your bivvy cover is waterproofed with a good sealer inside and out. Spend money on your sleeping gear. Good sleep will keep you going for a long time.
Next at least a 60 liter pack. Spend some reserve notes for a good one. Army surplus has great new gear. Ditch the Alice pack ASAP. Your back will thank you. External frames suck because if it breaks( most are aluminum) life gets shitty till you fix it. I have the Marines combat patrol pack. Best one I've had. Rei also has great gear.
Boots should be well tread and fairly waterproof. Wet feet + 12 mile hike= jungle rot. You definitely don't want to go their but it's not common unless you just never change your socks don't trip.
A good set of clothes that are heavy enough for cold nights and durable enough to last. I have one set of clothes. Pants ,jacket, hoodie, rain slicker are permenant. Socks, T-shirts,underwear and thermals are disposable and should be treated as such. You don't want a lot of clothes eating up food and cool stuff space.
A knife or smiley (something heavy and metalic thats tied to a rope or chain that you keep on you for defence against dogs, yuppie junkies and Cain wielding old ladies with poodles. Well maybe not the dogs.
Duct tape. Self explanatory
I don't carry any cooking equipment. I find myself in areas that aren't hobo kitchen friendly. It's easier getting hot food from yuppies. Your coffee maker may or may not work out. You figure for a cup of Joe you need pot, heat source, fuel, coffee and a cup, that's like 5-8 lbs. F that. McDonald's for a 1$.
Tarps are good to have, but, I just use a cheap 2man Walmart tent for those rainy nights or when chica wants to hippie cuddle. Privacy is a luxury out here. TBC
