I had Doug at
Casita Works install this beefed up version of his standard 150lb capacity hitch receiver on my
Casita SD a few weeks back. For liability reasons he didn't want to officially rate it for a specific load
weight but lets just say that it's easily capable of more
weight than the standard hitch. He said the frame would become the weak point before the hitch receiver itself.
I don't have any plans to carry anything of any specific
weight out back but I wanted the ability to push that load limit a tad and this certainly fits the bill. If you're interested in this HD version you need to reach out to Doug directly as he doesn't list or market this particular model on his website.
