The side rails and gussets were designed around our strengths. The picture you posted is one of 254's drivetrains, and while they have a fantastic design, we do not have access to the same resources that they do. They design around a welded aluminum frame, where as we depend largely upon gusset and Versaframe construction, due to a lack of machining resources.

You wouldn't even have to weld it you could use the versa hole pattern and bolt your upper frame to the bumper supports instead
