RE: Blowover
Sorry about your fiver. I lost the shingles on my garage here in Cheyenne yesterday, but that is small potatos compared to a fiver. Two of my friends lost their trailers on I-80 in the last 2 years. The Wyoming wind can be nasty.
RE: Black water vent pipe
I have a 2002 Cougar 295 and had similar problems when it was new. My problem turned out to be household toilet paper that built up below the pipe from the toilet to the tank. Ended up having a septic tank pumper pump out the tank. Had to use a high pressure toilet wand to break up the solids so the pump could pump it out. Now use RV toilet paper and lotsa water when we flush. I also would use a high pressure hose down the vent in case it's partially plugged.
