Camping to be or not to be?

I want to make a lame attempt to go camping with my two little ones. Joe won't be able to go but the rest of my family will be there. I don't know if this going to work due to some issues that won't go away. Joe's car makes a thunk noise whenever you make a hard left or right. It is not a bearing, it is not the CV joint, Universal joint or the brakes. The shop has had it for a week now and we NEED the car back. The Durango "eats" way too much gas for Joe's commute (did I mention he can work one day a week at home now!) Collin is at the end of being sick but last night Quintin decided to get some boogers himself. I don't want to camp with a little one just starting to be sick. His nose isn't running profusely so maybe we will get lucky and it will be a quick little nothing. Camping isn't looking too hopeful yet but like I said, maybe we will get lucky.
