We Fully Support DIY Installations
Unlike many authorized Webasto distributors, Vanlife Outfitters fully supports DIY installers. Our entire team has been trained to become Webasto certified "experts". Together with our distribution partner, we maintain a wide range products and replacement parts in-stock. If you experience a problem with your Webasto unit within the warranty period, we will work with you to determine the cause of failure and will either attempt to give instruction on how to correct any faulty workmanship or supply a replacement part. If a replacement part is needed we will send you the part immediately from their stock at no charge so that you can get up and running as quickly as possible. Of course, we rely on you to return any faulty parts in order to be reimbursed for the warranty repair.

Please check out our blog post about Webasto heaters, how to install them and why you should seriously consider buying them from us (or another North American distributor) instead of the amazingly cheap units from Russia!

Enjoy years of reliable heating with a genuine Webasto Air Top EVO 40 gasoline powered air heater!
