I guess so far all I have found is that the thing works well on a/c. The whole idea of buying the Roadtrek was to be able to boondock at race tracks for 3 or 4 days without running a gen. So I am particularly interested in the LP option.
At 5 PM I switched to LP mode. Nothing else was changed. Except the temp inside the rv has dropped from 105 degrees to 94. Within 5 minutes the refer temp increased to 27. The condenser tube I had been monitoring for temp dropped from 114 to 107. I was running a small fan on the condenser fins but turned it off when switching to gas. Without the fan the condenser tube was over 130 degrees at times. Time will tell.
