1) Get yourself some quality dry bags. I would recommend getting a few Watershed dry bags. IMO a few smaller bags are better than one or two large bags. You can find Watershed dry bags online for a pretty good price sometimes. Check Watershed Bags - eBags.com

2) Easy camp setup works well. I brought a jetboil stove and a small titanium pot for all the cooking. It's tricky to cook with the jetboil but it does boil water fast and doesn't use much fuel. Use the pot for cooking and the cup that comes with it for boiling water or making coffee. The large canister, I think it was 10oz, lasted me for a 9 days self support in the winter.
3) Fire pan and Groover, look at that website that lmeyers provided. There is good tips in there. I would recommend making a groover about the same as those guys did. It will give you enough room to be legal for a 12 day Grand Canyon trip. GC has the strictest rules regarding the groover and they do check prior to putting on. While the GC rules don't require you to use 6" PVC, I used 6" and it worked well. In the GC, you're required to have a certain amount of volume for you groover for it to be legal in the GC. I would use WAG bags on smaller trips if they are approved. The link has a table with the calculations of different sized pipe diameters and volume. Make the firepan so that's its easy to split up amongst the team. Self Support Kayak Camping
