I can tell you from experience that you'll probably never need anything that big. Unless you're traveling through some foreign country and living off the land you'll never use that capacity. I traveled 10 days cross country and I could have made due with a couple changes of clothes and a small tool kit. Buy some soft luggage and be done with it. In most places you can find food and a laundry mat... Just MHO...

I'm looking for basically 1/2 of what he has, but I want room to strap a tent, sleeping bag, and small folding chair to the top. I already have soft luggage, I was just thinking about upgrading.

derf I'll give you my Cortech saddle bags if ya want them... got some new bags on the way... they need some patch work... but they'll do for long trips... (I've done 3 with them) but they're like sponges in the wet... so pack your shit in zip lock bags..

Alright then... Kick ass and carry on.

I think the "quick release" or pita release is going to be the challenge. If it were me I wouldn't worry about the containers as much as the support mechanism... I'd prolly look for some old ammo containers actually... That could be badass and much easier...
