I bought a 16 ft trailer from Kodiak Industries and I was surprised at how durable it was. Came with a smooth, glossy finish, lights were fully functioning, and overall I really can't complain. Quality investment on my part.
I applied Kodiak's Rhino Extreme lining to my truck, and it works (and looks) great. Had zero problems installing it, and now I no longer get any scrapes or scratches whenever I'm hauling stuff around. Kodiak is good in my book!
