My wife and I installed the roof rack in a couple hours on our 177 2016 Sprinter. Orion provides a QR code that you can scan linking you to pretty foolproof illustrated instructions. The instructions were super easy to follow and make installation a lot less daunting! The materials are solid and very well made. The rack fits PERFECTLY on the van and we couldn't be happier. We also got the ladder, surf pole, and surf hooks. We LOOOVE them. The van is still a work in progress, but these additions are amazing. Thanks, Orion for making an awesome rack!
