Not sure what you mean by "similar GVWR".
Ford offers F-150s with GVWRs ranging from 6450-7700# (non-HD payload pkg) and GVWRs up to 8200# with the HD payload pkg.
There are variations of 1/2 ton Dodge, Ford, and GM trucks that have payloads anywhere from 1400 lbs, up to 2300 lbs.
The 2014 F-150 SuperCab with HD payload pkg has published payload up to 2710#.
The 2014 SuperCrew with HD pkg has payload of 2620#.
