I am seeking some guidance in planning a family of 4 vacation renting an RV in California. We would be newbies. Looking for guidance in Renting an RV (gas vs diesel) what to look for in the cost of mileage. Where to stay? please let us know what you suggest for Sedona, Grand Canyon area. Hooking up at a campsite, what to know or look for. Since we are traveling from east coast to LA, we will not have the opportunity to bring prepared foods. Any helpful hints on items to bring and stock up. Are there any websites you highly suggest for information? Thank you in Advance.
