Lake Charles, Moss Bluff, Westlake, Vinton and Iowa get daily coverage, and Cameron, Hackberry, DeQuincy and Ragley get regular weekly routes.
It works on rooftop air conditioners (it keeps Coleman, Dometic and Furrion parts on the truck), Norcold and 12V compressor refrigerators, Suburban and Atwood water heaters, furnaces, converters, inverters, 12V faults, solar charging and house batteries, slide-outs, awnings and electric steps, and plumbing, pumps and leaks. It also cleans black, grey and fresh water tanks and does solar installs.

A first visit costs $230, which covers the trip and the first hour of technician time. After that, labor is $155/hour billed in 15 minute increments, plus parts. For extended warranty calls, most warranty providers approve a $50 trip fee, and warranty labor is $195/hour. It handles the claim paperwork with most major extended warranty providers. Hours are Monday to Friday, 8:00 AM to 5:00 PM.
The owner, Garth Frenzel, is an RVTAA Master Certified Technician, a credential that covers chassis, electrical, plumbing, propane, appliances, exterior and brakes. His wife Monique runs the office side, and Service Coordinator Amanda answers the phone and keeps the schedule. It also serves contract workers living in RVs at job sites.
This is a good fit for an owner or traveler around Lake Charles and Sulphur with a failed AC, fridge, water heater or slide-out who wants the price stated before the truck shows up.
