Ok, clearly not a Siegmund or Strong Hand, but Harbor Freight is really upping their game lately.
The big table that he put together makes less sense to me. You're going to compound any accuracy issues the larger you go. But (like he says) I can see getting one or two and having the option to bolt them together or separate them for storage. I wouldn't be fabricating a chassis on them, but I could see the advantages of building sliders and bumpers and such on them.
It looks similar to the Klutch table offered by Northern Tools (but I don't have a Northern anywhere close to me): https://www.northerntool.com/produc...h-tool-kit-36in-l-x-24in-w-x-33-1-4in-h-61158
Interestingly, despite the video saying "officially launched" this has been about the only thing I've been able to find on it. HF's "new tools" doesn't mention it: New Tools - Harbor Freight Tools
And there is a reddit post on it, but the poster seems to have deleted their posts: Reddit
He has some more video on his Instagram:
