I have a failed Drainmaster dump value, so while I'm at it I want to change the old brown Drainmaster hose for the newer green one. The green one has a 4:1 expansion, rather than the 3:1 of the brown one - which would be very useful in some campgrounds. 

I can't measure the hose without removing it, something I'm definitely not doing until I have too! Newell has fitted 68" and 80" hoses according to Drainmaster. Any idea when the switch over was? I did a rough measurement on my coach #1277 and it came out to about 76.5", so I'm guessing its 80", but would like to be reassured before ordering. I'd also like to be able to tell Drainmaster an approximate coach number when the change over happened so its easier for all of us in the future.

Thanks in advance
Mick
