Thanks for chiming in I hadn't seen that feedback anywhere. The only downside now is to spend $600 on the Tanks in setup and still have to get a regulator and lines. But that's a small thing. I could also just go the fuel cell setup and use a different regulator
Another bit of good news. My brother is picking up a 2008 5.3 today with less than 100k miles on it from my Uncles garage for $250. So a huge piece of the puzzle is now purchased.
