When an RV needs body parts — caps, panels, windows, trim — you’ll often have a choice between OEM (original equipment manufacturer) parts and aftermarket or fabricated parts. Here’s how to decide.
OEM parts
- Designed for your exact model
- Usually the closest fit and appearance
- Often required by insurance policies on newer RVs
- Can be expensive or slow to get — and some are discontinued
Aftermarket and fabricated parts
- Often faster to get and less expensive
- Quality varies by maker
- Fabrication can solve discontinued-part problems on older RVs
- May need more fitting and finishing
What insurance usually says
Policies on RVs under about five years old often call for OEM parts. Your adjuster and the shop should agree on the parts before work starts. See RV insurance claims.
How we choose
We recommend parts based on fit, availability, your policy and how the RV will be used, and we put the choice in your written estimate. When a part no longer exists, we can fabricate one in-house. See RV collision repair.
Frequently asked questions
Are aftermarket parts lower quality?
Not always. Quality varies by maker; a good shop knows which parts fit and last.
What if my RV's part is discontinued?
We can often source an alternative or fabricate a replacement.
Will insurance pay for OEM parts?
Many policies on newer RVs require them. Check your policy and talk with your adjuster.
