That is going to exceed your trucks limits. Think fifth wheels under about 30 feet and under about 12,000 GVWR. The one I looked at has an advertised pin weight of around 2400 pounds dry! That will translate of over 3000 loaded pin weight. That puts them squarely in 3500 territory and honestly into dually country. While new trucks have higher weight limits, you will find as you go bigger weights pile up in a big hurry.
Columbus is a relatively new name plate with only an OK reputation. Check out Cedar Creek Silverback for an alternative.
