Just like your car, RVs use several different fluids to keep them operating properly. A Fluid Analysis is a separate RV inspection service for motorhomes or an RV tow vehicle that many people choose to add on. Samples of fluids are collected and then sent to a professional laboratory for analysis. Potential fluid analyses include:
Transmission Fluid
Engine Oil
Engine Coolant
Generator Oil
Generator Coolant
Coolant from Aqua-Hot or similar systems
