First off, thank you all for the replies, good information and I plan to identify in the future, everything discussed in this thread.
I stopped on the way home and bought a heavier gauge, shorter cord. I put the Fluke on the longer lighter cord and it read 122 volts at the camper, the heavier gauge, shorter cable also read 122 volts. Doesn't that indicate it is not a problem with voltage?
I fired up the unit and waited for ten minutes inside the camper, and was not getting any cold air.
I turned it off went topside and inspected everything, it all looked OK. Fired it back up and went up topside again. The fan ran for at least ten minutes before all of a sudden the compressor clicked on.
I was up there for another ten minutes before the as somebody mentioned, the the thinner tube begin to heat up, and the bigger tube begin to cool. After ten minutes more, the bigger tube did get cold, but not icy cold.
Inside the camper I did get some cold air. Now I'm not sure if the heavier cord, helped, if the unit takes that long to get going, or maybe the thermostat is the reason for the erratic behavior..if that is erratic.
I know most parks have a 30 amp and 50 amp plug-in, can you plug a camper into the heavier connection using the cord that looks like a 220? My camper has that sort of connection, I have just always plugged into the standard 110 receptacle using an adapter.
