1988 Excella AC Drain Problem

[68Glbtrotter]

I've inherited a 29' Excella that was winterized and I am preparing it for the summer. My first trip and the AC did not drain. I checked the tube and it is not blocked. Air comes out of unconnected end. The end on the inside of trailer is not connected. See pix. Pictures are of the inside AC unit with cover removed. 'Inside" end of tube is circled and 'someone' placed a clamp to prevent it from slipping back in.
Water drains from everywhere except the tube.

Suggestions?

Thanks in advance

This is where I had my problem and how I fixed it. Not sure yours is the same
model. It has not leaked in two years.
Can you see where the drain hose is supposed to be attached?
Hope this helps you.

I think my father replaced the AC and the drain tube is from the older unit. So does the Coleman 7300 drain onto the roof, w/o the tube? Are the pan holes stopped up? How do I remove the rooftop shroud?

If it just drains over the side, that's the way it's supposed to do. There used to be a drain pan for Coleman A/C units, but they haven't been available for ages.
As for removing the shroud, all you have to do is unscrew the 4 bolts holding the shroud on, and lift it off.

Thanks Terry
Unfortunately the water is finding a way out from the inside...bellypan or antenna screw or window seal and if I don't get it fixed, I'm sure I'll find more possibilities. But from your advice, I think I just need to lift the shroud off and check to see if the pan is plugged up. Agree?
