I love the larger screen and the longer lasting batters. Since I hated my eeztire set up I sold it with my last motorcoach. However, in researching your product, I came across all negative reviews on IRV2. I last one written a year ago last January. Have all the bugs been worked out of the TMPS units? Additionally, at $795 to make this work for my London Aire and Grand Cherokee you are at the very top of the price point. Are there discounts I do not know about?
