SUMMARY

The discussion highlights the advantages of dual rear wheel (DRW) trucks over single rear wheel (SRW) trucks, particularly for towing and stability. Key benefits of DRW trucks include increased load capacity, improved blowout protection, and better hydroplaning resistance due to the wider tire footprint. However, drawbacks include decreased fuel efficiency and challenges in maneuverability, especially in off-road conditions. The consensus is that for towing heavy loads, such as fifth-wheel trailers, a DRW configuration is superior, while SRW trucks may offer a better ride and lower operating costs for lighter use.

PREREQUISITES
  • Understanding of vehicle dynamics and weight distribution
  • Familiarity with towing capacities and trailer types
  • Knowledge of tire types and their performance characteristics
  • Basic principles of vehicle aerodynamics
NEXT STEPS
  • Research the towing capacities of various truck models, focusing on DRW vs. SRW configurations
  • Explore the impact of tire width and type on vehicle performance and fuel efficiency
  • Learn about the advantages of different axle configurations in heavy-duty trucks
  • Investigate the regulations regarding vehicle weight limits and their implications for truck owners
USEFUL FOR

Truck owners, towing enthusiasts, and individuals considering purchasing a vehicle for heavy-duty applications, particularly those interested in the performance differences between dual and single rear wheel configurations.

Off topic question i hope one of the truck guys may know. I think the answer is yes, but, do all dually's use a Full Floating Axle over a Semi-Floating Axle?

Based on my experience I would say yes. Haven't seen a truck with duals that wasn't floating.
