The Watson Chronicles - The Case of the Substitute Screw


RV: 2023 Class A Motorhome

Inspection Results: 3 MAJOR Issues; 14 MINOR Issues

This Case: The front cap access door to the engine compartment utilizes a stop post (typically Machine Screw Threaded) to keep the door from opening too far and causing damage to the front cap/wall.


The inspector observed that the stop bar was not present and a large screw (Sheet Metal Threaded) had been forced into the hole as a substitute. The screw is not as strong as the original stop post nor are the threads as secure as a machine thread with thread locker. This could easily fail due to normal road vibration.


Watson asked if there was a need to inspect new factory-direct RV's. To which the inspector replied, 'It is elementary, my dear Watson.' This screw may have been minor, however the major issues alone were worth the investment in a NRVIA Certified inspection.


I hope this installment of The Watson Chronicles was informative. If you are buying a new or pre-owned RV you can find an Independent NRVIA Certified RV Inspector at http://www.NRVIA.org.
