I'm considering that for this year. Might give me more peace of mind...
The other thing holding me back is that the spot where the water pump is is very awkward to access. You have to lift the bed to get to some of the screws for the panel. Once you do, the screws are in very flimsy, thin board and I can't imagine the screws lasting long before stripping too much of the wood.
Any suggestions on making spots like this and the water heater bypass more accessible? I'm debating putting hinges on them or something so they don't have to be screwed shut and unscrewed every time...
