During PDI on slide-outs, what alignments should be verified?

Verifying the alignments of slide-outs during the Pre-Delivery Inspection (PDI) is crucial to ensure they function correctly and maintain the structural integrity of the RV. The correct focus on alignments is front to rear and top to bottom, as this ensures that the slide-out is not only fitting properly within the designated space but also sealing correctly when closed.

When checking front to rear alignment, you're ensuring that the slide-out extends and retracts without any obstruction, maintaining a straight path. This helps prevent mechanical issues and excessive wear that could lead to malfunction.

Top to bottom alignment is just as critical; it guarantees that when the slide-out is closed, it sits flush with the main body of the RV. A proper top to bottom fit helps to create a firm seal that prevents air and water leaks, which could contribute to damage or mold issues over time.

Other alignments, such as left to right or open to closed, do not provide the comprehensive checks needed for ensuring the overall functionality and integrity of the slide-out system. Thus, focusing on front to rear and top to bottom provides a holistic approach to verifying the proper operation of slide-outs.
