There is gentleman who keeps his business utility trailer in the same storage lot where our AS is at. He has a mobile RV shop and we happened to see him at his trailer while we were there this morning. If you're a snow bird staying near the Houston area or don't want to hitch up and haul your RV to a shop, you might like to contact him. He's a certified and insured technician, including the Texas Railroad Commission cert. required for inspecting LP gas systems in this state.
Here is his website. http://www.na-rv.com/
