Pick up a copy of the Yuma White Sheets. It lists many mobile repairmen. Some should still be in the area after April 1. North Idaho RV Repair (Bob Bennett) has a good following in our park. Also Hilco and Foothills RV Repair have good backers also. As far as parks, at that time you will be able to get in anywhere. Depends how many amenities and space you want and how much you want to spend. All RV parks are not equal. If coming out towards the Foothills I'd recommend staying on the south side of I-8 as on the north side, the railroad is a super busy track. We have used Drs. Camacho for 12 years. They are just to the left of the border crossing in a gray block building. Their shingle says Pediatric Dentistry, but they do everybody. It is a husband and wife and I believe their daughter is now in the practice. If I can be of more help, just PM me. WE will be here at least until April 10.
