Mike, good to meet you. Camp WAMP is a great trip. The trail is not all that tough. If you have experiance you should not have a problem. A few things I would suggest. First remove the step rails. It is an easy thing to do, takes about five minute a side. Once you get back you can put them back on if you like. Second, everone will tell you to remove the brush guard. You do not have to do this if you do 2 things. Remember it is a "brush guard" and not a bull bar. The differance is that a brush guard is meant to guard the radiator from brush, not rocks, and make sure to take a look at the bottom of the guard where the bars go under the bumper. Know how far off the ground they are. If you hit one hard enough on a rock it could bend it into the hood. This does however take one hell of a hit to do.
Camping in the sierras is great. Make sure to bring bug spray, a set of cloths for cold weather, and sleeping bags that can keep you warm. It does not always get cold, but if you are not used to it then it could make for a rough trip.
Thats all I can think of for now. See you at camp WAMP.
