My wife and I spent three weeks in Puerto Penasco/Rocky Point in November of 2012 and thoroughly enjoyed it. We pulled a 26' travel trailer down from Phoenix through Gila Bend and Ajo, AZ and went back up through Yuma the Sunday after Thanksgiving. If you're in California cross at San Luis south of Yuma and take the highway south toward El Golfo then continue southeast on the coastal highway to Puerto Penasco. We found the roads to be in good condition and enjoyed the drive. We stayed at Playa Bonita RV park http://www.rockypointreview.com/ad11324.html and would recommend it. We later checked out other parks but found Playa Bonita right on the beach the best for us.
