I ordered the optional tank heaters, which consist of adhesive backed pads stuck onto the bottom side of both waste tanks.
Here's what they looked like when new:
Now they are literally half hanging off. Right at one year old. We're heading up towards Topsail Hill this Friday, and if it ever stops raining after work, I'll take a picture of their current condition before fixing them.
I plan on cleaning the tank and pad with a little alcohol, then using "Shoe Goo" adhesive to bond them back to the tank. This is really good stuff and I suspect it'll be permanent.
Waves of rain hitting my skylight at home at the moment.
