Re: camco winterizing kit
I had a similar experience, checked the engine drains and found not much AF in there, so I drained and backfilled and have been doing it that way for years. I also think it's good to remove the drains every year so they don't get rusted in place, I put some OMC triple guard grease on the threads and they come out easy every year. I use -100 just in case there is some water than didn't drain, it gives freeze protection down to about -50, used full strength.
