How do Off Road Beasts Come to Life?Our Build Process in 3 Easy Steps

Every Custom Build or Restoration has a simple three step process we follow to ensure your custom 4x4 or restoration project is completed to your total satisfaction.


The customer always knows what they want from their vehicle. We strive to bring that dream to a reality by sitting down and consulting on an approach to bring the concept to a reality.

Design and Build

RSO Breaks down the vehicle to inventory everything that is needed to get the Job done. Then we get to work on designs for your approval.


When the vehicle is complete, it is tested and delivered to the customer. Great care is taken to make sure the vehicle is in perfect condition upon delivery.
