Thank you for your inquiry. Unfortunately, we don't work on travel trailer. You might try Sumner RV
Try a RV facility. WCTT is for semis etc.
I seriously doubt it for two reasons. First they mostly work on tractor trailer equipment and not recreational. Second by gas I'm assuming you mean propane? Huge liability and again way outside their norm. You're gonna need a mobile mechanic that knows propane. Try talking to propane services.
Thanks! Your answer is awaiting moderation.
