3 friends and I are planning on a road trip from Northern California, through San Diego, New Mexico, Arizona, Texas, and Louisiana and back during the summer. We will be traveling in an RV, and stopping maybe a day (at the most) in Texas, Los Angelas, and New Orleans for 2 or 3 days. Can anyone suggest about how long should we plan for the trip to be, and how much money we should each bring along for everything (not including gift shops, etc. Just the essentials)

Thanks
