Taking off for Bull Run Regional Park later today for our 'dewinterization' campout. Will get all
the anti-freeze out of the system and make sure everything works. One problem already - the toilet
won't hold water. Will have to take it up and replace the seals. Oh well, that's why God made rubber
gloves, I reckon.

Hopefully I won't break something else!

Oh ****! I forgot to drain the antifreeze.

Try spraying a little silicone and see if it softens the seal.
