I went the WAY less scientific way of looking at the two kids camping in VehiCrossAmerica, where they've taken road trips from Alaska to Arizona and Alaska to North Carolina over several years. That's tested plenty for me to have made my decision. That speaks volumes to me about weight capacity, road worthiness of the VX, and quality of the Tepui product. JMHO

Also, Ryan (previous owner of my VX), had a full Yakima extended rack with; 4 Hella lights and mounts, CB antenna and mount, Hi-Lift jack & mount, and tire lock mount with a full size spare matching those in my description (which weighs way more than 110lbs alone) on the roof, and it stood up to road trips with that stuff too.
