[Trailer Trash 2]

at our last campground our microwave seemed to be working odly, we had the usual items on, the MW seemed to be working on low voltage where a regularcup of coffee took 2 1/2 times on beverage to heat the cup of coffee.
if I put the water heater and frig on propane then use the MW it works fine, now this was at our last KOA camp the new one we are at now does not do any of this, I just have 20 pounds of water pressure from them but good voltage.
any comments on this would be nice.

Thanks Don.
