We have a mobile tech or 5 at the park that I call mostly home. He likes all of us fulltimers/snowbirds, follow the weather. He lives in Colo during the summer heat, and in our neck of the woods during the winter. He is without doubt the most reliable of techs (or as some call themselves, rv repairmen) in the area. I and many others put off our repairs that we can live thru, until he arrives in Oct. From Oct thru Feb, he is constantly busy. Even the rv places in town recommend him over their own shops.
That is what you need to strive for.
