The quick drain plugs for the block and manifold look great! The only other PITA remaining is the heater. I hated the shower and removed it since we never really used it.

Skidim used to have a drain kit...I don't see it listed now (or maybe couldn't hit it with search) - had two manifold drains, two block drains and a raw water elbow drain. Worth every nickel. Attach about 4 inches of fuel line in each manifold drain so the water goes into the bilge and not onto carpet.

The heater is not hard once you have a little system - just do it when it's warm...soooo much simpler. I have a squeeze bottle like below for the antifreeze...after i blow out the line, I just squirt some in the hose, blow again to mix and - wallah! - done!
