Reg, despite my little shenanigans, I seriously thank you for the window gasket idea.
You're a great builder. Your plumbing looks awesome. You even painted the ball valve hand red. That's an eye for detail. So all these log trucks seem to have water tanks on them. Forest fire prevention? Hard to see how a diesel would start a fire in the woods, but it must have happened enough...?
And thanks for the link to the H-gasket material Ken. I'll have to give that a look!
