Testimonials
Highly recommend HTV
My wife and I just got a high-top roof installed on our 2000 Ford E250, and it completely changed the van. Micah and Lindsay were very nice, awesome to work with, super knowledgeable, and full of helpful tips for our future build.
Top notch, quality work!
Micah and Lindsay were amazing to work with. I had so many questions that Micah patiently answered. He even made recommendations for parts that had nothing to do with the top just because he wants people to have a good experience with their vans.
I couldn't be happier
Micah and Lindsay were absolutely incredible to work with. You can tell right away they take pride in what they do and truly care about their customers. They are some of the most genuine and authentic people I've ever met.
High Top Vans, do I recommend HTV's, absolutely!
Micah is meticulous, I realized when I saw his tool chest, ridiculous organization. They installed and wired my solar panels, roof penetration, prewire Starlink, solar breaker, MMPT solar controller, DC to DC charging, shore power, wire batteries, Lynx distributors, Cerbo GX, air conditioner, MaxAir fan, ran power to my 12V and 120V electrical panels.
High Top Vans does great work and I highly recommend them.
I called on Monday they had a opening in there schedule and the top was installed on Thursday. Micah and Lindsay are very knowledgeable and gave us much insight on continuing our build.
Highly recommend HTV I love my new top
Micah and Lindsay were both amazing and super helpful with any questions I had. The top was installed in 6h with a new max van too!!! and only 1 week after my initial contact still can't believe it...
We love our High Top from HTV.
Micah and Lindsay were both great to work with and super helpful with any questions we had. We spent a relaxing day in Camas Wa while they worked their magic and we couldn’t be happier. We 100% recommend HTV for your van build needs.
