We haven’t taken our first trip yet, but so far, we’re very impressed with Brinkley’s attention to detail and quality. There’s no such thing as a perfect camper, but you can tell they try really hard to be innovative without cutting corners. We’re happy with our decision!

These people are the best!! And the quality and workmanship for a camper is unbelievable. I slightly damaged the front wall in my garage and these people took very good care of fixing this. I can't say enough good things about them.

We've owned 14 various RVs in our 42 years together and Brinkley is the unicorn! It is by far our all time favorite RV.

I’ve been working on RVs for about 17 years, and Brinkley’s attention to detail is some of the best I’ve seen in a long, long time. Overall build quality is excellent. Of the roughly 12 units I’ve worked on, most issues were user error, and the others were components, not Brinkley construction. Glad to see a company building a QUALITY camper!
