the couple issues with my design that pertain to this are
#1 - the tiedown rail really messes with this... whether just hard mounting a vise on top, not doable now, unless I shorten the rail at like the one corner..... but I'm not crazy about the aesthetics there... or even bolting up that mount for the one you posted.. that would have been better, cuz than the vise is storable/safe/secure..
#2 my receiver is relatively low.... AND.... with the tubegate angled back, potential issue there..
we'll figure out the best approach when I get that far... heck, I still need to build the receiver section and it's bolt-in bracket up to the gooseneck plate too...
but I do like the idea of a slide in mount that would bring it out past the tubegate, and up to a reasonable height... obviously in a pinch, right in the receiver would get it done for ya..
but if I'm working on site, all day, my back will definitely appreciate it at a waist height!
to be honest, not exactly sure when i'll start that fab... could be as early as march or april, when I drag the bed out of the LAB™ and bolt it up on Mutt... or, it could be june/july.....
