Coleman Xtreme cooler-this thing is double insulated and a must in the desert. You loose a little space because the walls are thicker, but when you can have a block of ice last over 5 days-it's worth it!

REI-they may not have the cheapest prices on everything, BUT they stand by what they sell. We have had zippers bust on tents and they have replaced the tents (several). After 6 months (4 trips) the sole separated on my husbands new boots, they replaced them. And if you join their co-op, you get back a bit of what you spend there.
Some of our favorite stuff:
BIGBENDCHAT.COM-If you are heading down to Big Bend, then this is the fountain of information you have been looking for! Read trip reports on just about every trail there, get great tips on hydration, gear, hiking....anything and everything having to do with the desert.
RUBBERMAID ACTION PACKERS- these storage boxes rock! We have three large ones for all our gear and one small one for kitchen pots and cooking gear. you can also use them as a table or sit on 'em.
CAMPMOR.COM- cheaper prices and they don't hammer you on the shipping. They have a wide selection of all things for camping. If you don't need it right away then this site is a great place to stock up on your supplies
THERM-A-REST-self-inflating, insulated sleeping pads. I hated to camp before we found these. You can adjust the firmness by adding a few puffs of air and they block the cold from the ground. They also don't deflate during the night like an airmattress does. Just unroll, loosen the cap and let them fill up on there own. I won't camp without one. They come in all lengthes and thicknesses, from lightweight for backpacking to luxury thick for car camping.
backcountry camping for the whole family
currently testing the Yeti cooler: results coming soon!
