Sprinter Capsule

I had an issue with one of the capsules, and I was called and they immediately corrected it .
You can judge a company better by their customer service response when something goes not as expected . They get an A plus for their service !

Simply The Best

When I got my van, I knew I wanted to sleep sideways but knew I needed flares. After months of research, I landed on the VanSpeed Capsules. It is hands down one of the best decisions I've made for my van. Between the capsules and the TrimRings, its the perfect addition to the van.
