Nigel, don't know where you improved the air flow or not, but from the pictures, you sure got the "BEER MOD" down pat. Looks like you need a larger ladder to just hold the beer
I was looking at a room "Roll Around" ac yesterday that you can sit in a corner near a window for the exhaust of a 6" hose. It was 110Vac @ 9000
BTU for $289.00. Pretty neat for a portable AC. Was not very large in size.
It is encouraging that the air flow to the bed room increased, at least it will be "COOL" zzzzzzzzzz's
Anyway, let us know in a couple of days if you can see or feel any different in your AC performance? At least it will slow down the evaporation of your beer
Sort of surprised me that your AC is all the way in the rear of your fifth wheel. I guess different models are changed in the way the AC is installed.
You and the Navigator have your parts of the US turned around for your visit. You are suppose to be in New England in the summer and in Carson City in the winter. Someone else mentioned it was 110° near Carson City.
Nigel, It has been hot just about anywhere you can be.
