After my trip to Oliver and then 2.5 weeks in South Utah, in 109 degree heat, I returned home to NH. Air-conditioning use was heavy during the trip and after being back about a week I had to relocate the trailer from under tree shade to direct sun, so I turned on the AC to keep it comfortable. Two hours later I went in and found it was 92 degrees in there. So I shut it down, checked everything inside and couldn't find anything amiss so I made my way to the roof. Upon removing the AC cover I found that one of the 3 fans blades has ripped off, after further investigation it seems that one of the mounting bolts let go, causing the other two rubber feet to tear through and break allowing the newly unsecured mini propeller to attempt a takeoff into the cover housing only to come crashing back down into inside of the cooling fins, this causing the blade to break.... Having been thinking about it anyways, time to order the hush kit, installs easily enough and while somewhat more quiet on my unit it was nothing drastically so, I did not find that the original equipment was that loud to begin with and I'd asked others during the trip, bring concerned about the complaints read here, no one thought it was an issue either. Back to the fail, if you are up there, I would recommend checking those mount bolts, remounting that fan was a bit involved as I was unwilling to break the seal where the unit secures to the roof, this the room for tools is extremely limited. Another thing I would recommend to all is to make cleaning the AC fins a part of your yearly maintenance, more so if you travel to dusty areas that would warrant it, as that fan having to pull air through them can add quite a bit of the noise to it with all that resistance built up from being dirty/clogged.

John, don't look. And actually when I took it in for fiberglass repair, in June, they were intrigued by it and asked questions about the setup. You are correct with your numbers, the in to the out parallel distance is 9.5" I prefer to use the premade guides so I don't kink them.

I took it back to Oliver, while I am the second owner and it was beyond its one year warranty period, they are stand up enough that they repaired it under warranty. In the earlier models the mount configuration for the rear power jacks had some issues and allowed movement, that cracked the fiberglass around the hole it goes through in the hull. They realized that there was the potential for an issue and reconfigured how the mounting is done sometime spring 2015.

Ah, I was wondering when you might reply on this thread. Then I finally noticed that you had merely hijacked my reply! I considered it no big deal and just wrote it off to the fact that they probably didn't let you guys have oxygen in the A-10. But my pearls of wisdom are now lost to humanity, much like the Ancient Library at Alexandria. The world is now a lesser place.

If there is something that any of you think will make the Forum more user friendly, just PM me. I always have a lot of work to do for all the Oliver companies and cannot stay on the Forums much, but if there is any kind of issues I can take time to fix them. I have installed a script that will automatically open external links in a new tab, so there is no need to do anything. Hope this helps.
