My biggest/longest road trip yet.

Totally fine at highway speeds? How does it handle rain and snow?

I have a Softopper on my Ram 2500. At 70+ mph, you can definitely see the wind pushing the sides in, but the hardware and fasteners have all held up fine over several years of use. Heavy snow on top will definitely stress the frame - if you park outside with heavy snow regularly, you'll want to brush off the snow if it's more than a few inches. The truck primarily tows a fifth wheel all summer, so the ability to quickly remove it without help is super nice.
