The promise of an “integrated motor/gear box/linkage” (IMGL) was particularly appealing, suggesting fewer potential failure points. My initial reaction was a sense of quiet optimism – a feeling that this could finally put an end to the step saga.

Real-World Testing: Putting Lippert 379145 Kwikee Step Motor Conversion Kit For “A” Linkage to the Test

First Use Experience

The testing ground for this conversion kit was my own workshop, a space that often doubles as an impromptu RV repair bay. Installation involved working primarily on the RV’s undercarriage, a familiar environment for anyone who’s done their own RV maintenance. The kit’s components are designed to fit into the existing Kwikee step assembly, specifically those utilizing an “A” linkage system. The instructions, while detailed, are best followed with a solid understanding of basic mechanical and electrical connections.

In terms of performance, the initial deployment and retraction cycles were smooth and noticeably quieter than the original setup. The integrated nature of the motor, gearbox, and linkage seemed to translate into a more unified, less hesitant operation. I paid particular attention to the door switch activation, ensuring the steps deployed upon opening the RV door and retracted when it was closed – a fundamental function that had been intermittently failing.

There were no major surprises during the initial installation, though ensuring proper alignment of the new linkage was key for smooth operation. A slight quirk I noticed was the need for precise positioning of the new motor assembly; any significant misalignment could lead to binding. This conversion kit is definitely a job for someone comfortable with a wrench and basic wiring.

Extended Use & Reliability

Over several months and numerous trips, this Lippert conversion kit has proven its worth. The steps have deployed and retracted consistently, regardless of weather conditions or frequency of use. I’ve tested it in dusty campgrounds, during light rain, and after the RV had been sitting idle for extended periods, and the performance has remained reliable. The previously intermittent grinding and hesitation issues are now a distant memory.

Durability appears to be a strong suit. Despite the vibration inherent in travel and the occasional bump from road debris, there have been no signs of cracks, stiffness, or performance degradation. The motor housing and linkage components show minimal wear, even after dozens of cycles per day during busier travel weeks. Maintenance has been refreshingly simple; a periodic wipe-down of the moving parts and ensuring the pivot points are free of debris is all that’s been required. Unlike some older step mechanisms that could become stiff or seize up, this upgraded unit has remained free-moving.

Compared to my previous experiences with older, original Kwikee motors and various generic replacements, this integrated kit offers a distinct advantage. It feels like a more robust, purpose-built solution that addresses the common failure points of earlier designs. While premium, entirely new step systems exist, this conversion kit offers a cost-effective way to revitalize an existing, well-integrated mechanism.
