The truck is a 2013 F350 CCLB SRW. Tires are Nokian Rotiiva AT Plus rated at 3750 pounds. Fully loaded with water, propane, food, fuel and DEF we are 12,380 pounds but under both front and rear GAWR. Perfectly balanced.
The trip was a big success. The Igloo fits us and the truck (and 2 dogs) perfectly and we are ready to head to Alaska in May.
