We opened up the popup this weekend to prepare it for our Keys trip in a couple of weeks and the A/C no longer cools
It was working great when we left the Fort a month ago. This is our 1984 Coleman that we remodeled - I think the air is original - so that puts it at 32 years old. Everything I read says to replace if it's over 10 years and, well, here I am. Camping without air is not even an option - even last New Year's at the Fort was in the high 80s.
We first tried to find a used one and there's one for $300 not far from us but what's the guarantee it will work? Miami isn't a big RV town so there are very few places for repair and only one guy that says he has them...but he charges TWICE as much as I see the same ones cost online (plus tax). Our canvas is relatively new and in great shape so I'm hesitant to cut it to install a window unit or the exhaust hose plus we are very pressed for weight in our towing vehicle (6 of us) so I don't think I want to carry this additional weight in there (unless I'm overthinking this too much).
Anyone have experience buying from somewhere online? I'm looking at 13.5K BTU. I'm worried about damage in transit and then customer service if, God forbid, something was wrong with it when it came. Thanks for any advice.
