You'll be able to find anything you need in DFW area. I tend to pack way too many things like you, but if I had to keep it to a minimum I could easily get by with the following;
2 REO's with fresh builds wicked with ready x wick, 3 30ml unicorn bottles of juice, a charger and an extra battery for each mod.
That got me through and extended weekend in Phoenix a few weeks back and I took way too much juice. I took more than that, but that's all that I used. I could cut that to only one REO, but I usually carry 2 with seperate flavors and switch back and forth through the day.
