I currently have a Doran Pressure Pro Monitor along with 10 tire sensors. I have did a search here for VMSpec and see that the latest beta version of VMSpec supports pressure pro. I see that you also make a monitoring device to replace the Doran. When do you expect to have them back in stock? P.S. Martin, it's been over 3 years, and I am still looking for VMSpec to support USB without the comm device. Just checking to see if any progress is being made. It's time this becomes a priority. I know in your last message to me, your primary business was dedicated to new coaches. However, with the increase of fuel, and the fact that many motorhome builders have folded, and others are hanging by the shorts, how about putting some emphasis on this much needed improvement.
