Chandler diagnosed our tricky propane leak in under two hours--we found him after dealing with another mobile RV tech that wasn't able to find it after almost a month and then denied that we had one! We found out that Chandler is certified in LP and he did a combination of a soap/water check and manometer testing as opposed to just an LP sniffer like some mobile RV techs seem to do. He was friendly, timely, and extremely professional. We'll definitely call him again if we have any other problems with our camper van.
