I found a great product for HUMMER owners. I know we all are feeling the pain at the pump. This product would be very helpful to us all. Not only do I drive a HUMMER, I work for a HUMMER dealership. So I'm feeling the pain at the pump and in the showroom. Don't wait for GM to come out with a Hybrid or Diesel H2 or H3. I've been to several meetings with GM and it's not going to happen. Take a look at item #230251110555 and 230251109954. This product is available for the H1, H2, H3. I will be listing the H1 version soon. Please read the testimonials and look at the video.
