Jclaine,

Similar to my Canadian version of the Streamliner DLX, but with reinforced plate gussets (lower part near the axle are thicker) and the load ratings are much better than mine!! This might be what you need. Not sure why my model is no longer listed. Perhaps this model had superceeded mine and looks like it shares some design commonality with my Old Man Mountain. Price pretty good for this pro quality rack.
