Recreational Vehicle Expert Witness Service
Who Are We?
Paul and Mao Unmack are Professional Engineers and apply engineering science to extensive RV and automotive experience. We are committed to RV safety and understand the systems that can fail due to many issues in RVs that result in damage to life and property. Practical experience combined with academic knowledge to understand failure modes is needed to win a case.
About Photo: We chose this photo because it reflects the fact that we live in our RV for extended periods of time. We live a life of adventure, therefore we understand how to not only maintain and fix the systems found in all RVs, we use them on a daily basis.
When we started practicing RV expert witness science, we came to find in short order that a majority of the experts had very little practical RV experience. This resulted in experts making decisions without relevant information or knowledge based on the complexity of an RV. Without a working knowledge of RVs, a holistic approach was not taken in order to advance the case toward a desirable outcome.

Design of Experiment and Proof of Accident Facts
The video above is a test that we designed to counter a claim that was made. The desired outcome was a simulation of the conditions required for the claimed failure mode. With application of the laws of physics combined with instrumentation to document the test we proved the failure mode for the part in question for this case.
Upon request we will provide an expert rebuttal report that contributed to a favorable settlement in this particular case.
