Our 2016 had this problem our first night in Baja. We were parked facing directly into the wind but the wind was in the 60-70 mph range. From then on it made popping noises in as little as 15 mph winds and it didn't seem to matter what direction it was facing. We returned it to our dealer who returned it to FWC and they repaired it.
Occasionally there is still a little popping but it is much improved. I didn't mention it is a 2016 Grandby with Yakima
tracks and a 160 watt solar panel.
