Just got back tonight from a family trip to BC. I was almost overwhelmed by the amount of diesel 60 and even a few 80 series I saw up there. I stopped by RADD Cruisers a few days ago and looked around. Very cool - I'm totally convinced I need a 12HT for my rig now. They claim they are getting up to 30 mpg on their 12HT which is better than my wife's dam hybrid! Plus the pulling power on hills and they sound pretty cool as well.
