Frequently Asked Questions

Q: How do I know if my left arm needs replacement?
A: Signs include difficulty extending or retracting the topper, visible bending or cracks in the arm, grinding noises during operation, or the topper sitting unevenly. If one side moves slower than the other, the left arm may be the culprit.

Q: Will this kit fit my Dometic SlideTopper?
A: This part is designed for Dometic ST Series SlideTopper systems. Verify your topper model before ordering. Check your RV documentation or the topper itself for the ST Series designation.

Q: Is installation a DIY job, or do I need a technician?
A: The left arm kit bolts directly to your existing SlideTopper frame. Most RV owners with basic mechanical skills can complete the installation in 1–2 hours. Consult your Dometic manual for torque specifications and step-by-step instructions.
