Phoenix Area Mobile Tech Recommendation

[LairdT]

I have a friend- a newbie to the RV world, - limping into he Phoenix area with her newer B+ experiencing multiple electrical issues. I was going to help her but got called to Colo Springs for a family medical emergency. So now my wife and our (single female) friend need to find a repair source. My experience with established dealers at this time of year is long waits to get in and you have to leave your rig for a week or so.....
Anyone have a recommendation for a mobile service in the Phoenix area???
