That's a great idea, thanks for sharing with all the detail. My 32TSBH only has the one AC and dealer said it couldn't be outfitted with a 2nd AC. We once camped in 100F weather. DW couldn't take it after one night. She packed up the next day and went back home with DD. home is only an hour away. DS stayed with me another night and then he too wanted to go home. Wish I had thought of your mod back then.
Me, DW, DD, & DS

I live in a big box but save my money to vacation in a small box... and look forward to every chance I get!
