I had eluded to this in another thread maybe a year or so ago, but finally noticed Dave say "818 Gen 2". I have not seen this nomenclature elsewhere and was curious if there would be some sort of improvement list or gen 1-2 comparison information available. Right now the only info seems to be from the end users posting about various changes to the tank, pedal box area, etc. Not only would this help with marketing, but for someone interested in buying a second-hand Gen 1 kit vs a new Gen 2 it would be very helpful. Thanks!
