Jay,
I think any 14 ch. FRS radio will work. Radio Shack has them. Probably the best of the bunch is the Kenwwod. Don't know where to get them but Rich and Zderf just bought them so they would know. You're right we have plenty of tools so other than those who said they were bringing tools there is no need. I don't have a good suggestion for a spare tire. I think it would be easier to buy one along the way if need be.
