Sorry about your experiance at PS Oasis. I've been there for over a year now and we have approx 70 to 90 Snowbirds that have been using PS Oasis for up to 20 years now, and I haven't heard of anyone loosing anything to bad power. It is an old park, built in the 70's, but still a very nice park with alot of great people in the winter.
I appreciate and respect your opinion on this park at Palm Springs but the bottom line is, yes, it's an old park with old wiring. When we pulled in there, a person on the next site from Wisconsin said he was pulling out because he just burned up his microwave because of low voltage. We have found many people have no idea what kind of voltage they are dealing with in parks. The lower the voltage, the higher the amperage and the more heat is created on all your appliances. We had a work camper come and see us when we were there as the office sent him over. He verified the park has a problem with the electric. I would say the office would never say anything about it. As I said, most people have no idea what the voltage is going into their unit as they don't have a voltage meter. I have a 40 ft MH and no way would it run safely on the power which was provided at the post. Many people just don't say anything and try and live with it. Encore do not maintain their parks very well. Anyway, I was really upset when the work camper said that's as good as it gets here sort of thing and drove away and so did I.
This has been my experience there.
