FAQ

What are your shipping options and costs?

We offer shipping to the USA and Canada, with many items qualifying for free shipping. Shipping costs are calculated based on weight and size at checkout. Shipping estimates are provided during checkout, and many products ship fast from Elkhart, Indiana.

Do you ship internationally?

We currently ship to the United States and Canada only.

What is your return policy?

Items that are eligible for return can be sent back within 30 days of delivery for a refund, but will incur a 20% restocking fee due to the custom nature of many products we carry.

Please note that many items are not eligible for return—including RV holding tanks, roller shades, and other built-to-order or special order items.

All returns must be pre-approved. To check if your item qualifies for return and begin the process, please use the AI Parts Chat on our website.

Can I cancel or change my order after placing it?

Because many items are custom-built or special order, cancellations are not always possible. Regular, non-custom items may be canceled if they have not entered the shipping process yet. Use our AI Parts Chat for quick help.

How can I track my order?

Once your order ships, you'll receive an email with tracking information.

Do you offer OEM parts?

Yes, we specialize in OEM RV parts from trusted brands like Lippert, MORryde, and Spinweld. You're getting factory-direct quality parts, not generics.
