I also sent an email and am very interested in the group buy, they just wouldn't make a product if it wasn't in-line with costs of other tanks, yet i'm in with the purchase just the same.
I only live about an hour and a half south of Transfer Flow, so i'll have my installed by them. Now lets wait on price and see how happy that makes us all. I still want one, i just hate filling up every day when driving alot, but it beats the cost of my old Diesel, stock they are both similar driven easily they get great mileage, yet lean on that accelerator and the fuel consumption goes away, and the Tundra wins that war easily, still getting better fuel mpg, and not leaving soot trails everywhere, hahaha.
Count me in on the Group Buy.
