"I recently bought a complete kit from SergSupply for my new Sprinter van. I couldn’t be happier! Thier workmanship is fantastic, prices are remarkably low, customer service is simply the best I’ve ever seen."

Greg Miller

"Great product! Very well made and the team was very helpful throughout. Prompt responses and very knowledgeable. I've had no problems at all. Would highly recommend!"

Albert Rodrigue

"I can't even begin to explain how incredible these kits are. Their team is super flexible and easy to work with. Literally makes the hardest part of doing a van build fun and cohesive. The pieces fit together perfectly and the customer service and response time is unbeatable."

Chase Coffin

"The quality of the work was outstanding. They made adjustments and accommodation for my low roof Sprinter and were very generous with providing materials, thoughtful instruction and creative solutions - will absolutely work with them again on every van build!"

Cambrea Ezell

"I have purchased several other items. I would have to say there customer service is excellent and top notch. Also a lot of other companies can learn from them and how to deal with customers and customer relations."

Bryan Livingston

"So far so good! We installed these last week and they look great. The customer service was outstanding. Most agreeable and helpful. The rings arrived promptly, as promised. Thank you!"
