I'm pretty OCD about the receiver fit as well. On most decent sets, the wedge (or Aero's tension screw) does the trick. A thin O-ring on the front lug works in most other situations. Get a decent set of takedown pins as well.
We use the exhaust fan consistently but it sits at ceiling level so I have to wonder how much it actually helps as the skylight is another 6' above the fan. Plus, the edge on the skylight opening is closer to the shower than the fan by at least a foot. I've been asking the primary user of the shower to leave the door open after done but that's throwing water in the wind because children... Also, the skylight doesn't open, which begs the question: what's the point other than making things unnecessarily complicated? Last, I suppose I am also to blame here as I drill out the shower head restrictor openings more than stock because the pressure is terrible so there's more water flowing to create steam, etc.
Made a visit to the Makepeace Lake WMA range Saturday morning. Some A-hole shot up/dumped a giant projection TV at about 15 yards.
This kind of stuff drives me crazy. I like to help clean up there and leave it better than I found it and people that do this kind of thing ruin it for everyone else!
