Hey 3 Pin,
I don't know how much time you have allotted in the area or how far away from the camper you want to get but just before the damn on the California side there is a small campground on lake mead in Boulder City, it's nothing to write home about but it's convenient and close to one of the best river trips you can do. I have lead the trip professionally twice, done it once personally and am planning to go back and do it on paddle boards very soon. It is a flat water, no water skills necessary float through Black Canyon which is the stretch of the Colorado river just below Hoover Dam, literally you put in staring up at the dam. What makes it great is that just past put in on river right is a sauna cave, you hike back into the rock below the dam and it is a natural 120 degree sauna with benches cut into the wall and as you leave there and float the rest of it every single side canyon is hot water. Pick one and hike up it and you will find a hot tub waiting for you. Some of the larger ones have sand bags to make them deeper and ladders and you can relax in a tight slot canyon hot spring with a sliver of stars above you as late as you want. It's an amazing spot, takes 3 days.
You can rent equipment and get a shuttle from these guys http://bouldercityoutfitters.com/rental.php
The navigation is simple float the flat water down stream for 3 days until you see a large boat ramp on your left, then get out and get on the shuttle bus which will take you back over the dam to see the bridge and back to your truck for the rest of the trip.
If you have time, check it out this time of year is the best as it gets way too hot to do it in the summer.
Have a great trip!
