Dead Roof AC. Need Advice....

I am impressed with my new Coleman chessie4905 a lot better unit the Penquin 11 was.Bob the Chinese are making their way into the RV market.

I looked at the Gree RV roof top and was impressed with the features plus it was low amp (13) but could not bring myself to buy it and Gree is the largest manufacture of mini splits AC's in the world they make the splits under dozen of different brands so the technology is there but they choose not to use it on RV roof tops

going to check it out. I know they are building the inverter roof tops overseas for the caravan market there. 50hz instead of 60 though. Glad to hear Coleman has come out with a new product. Maybe Nick can give us some more info on it. Bob

I've got 3 Coleman Mach low profiles installed in 2001. Still running strong. They are ducted. I only run them on low as the high speed just isn't needed. They work really well, and I hope when they die I can get another that is similar as I would hate to tear out all my ductwork.

David, Could you provide some info on the duct work? Thinking of replacing both of our rooftops and like the thought of quiet.
Thanks,
Dennis

This is what Penguin did to raise their 13,500btu unit to 15,000btu. Same everything, except higher capacity fan motor. Good Luck, TomC

Is anyone using the Coleman Roughneck AC units?

I have 2 of those on my Eagle, it was over 100 deg here today and I had them on low, I was in and out of the bus all day and it still stayed nice and cool.

Mark,

I have 2 Coleman units now. 1 is the Mach 8 15k with heat pump and it does a good job. The other is a Mach 3 13.5k unit and it does good as well although I think the armature for the fan is either slightly bent or off balance and while it works great it sometimes needs a little love to get started.

If I can come visit you around the 21st I'd be glad to help you get your AC straightened out. My 15k dumped water in the bus and I had to take it apart and found that one drain tube was run incorrectly and one of the drainholes in the unit was not drilled out. Easy fix. Then I found that a couple of the rivets were loose on the plate that covers the cutout on the bus and some runoff water was leaking in (also when it rained).

I think I'm going to order a new AC unit for the bedroom and I'd be glad to give you my 13.5 if you want to take a look at it. It works as well as the 15k unit up front.

The Advent seems to be a decent AC you see a lot of those on new RV's fwiw

Bought two new Atwood 's last month. Haven't got them installed yet, replacing my 12 year old Carrier 's. Have saw way too many of the new Domestics and Coleman 's die running 24/7 when the temperature get into the teens..rdw

Thanks Sean! I know we've talked about your mini-split dilemmas and that you eventually gave up on them and went to roof tops. Would be good to see you again, and have an AC chat! I have a meeting on the 21st, but I'm free all day on Sunday the 20th and can come out to see you.
