I made a Paul Seller's bench from 2x4's several years ago, I use it all the time and it works great. Mind you only the end with the vise is still clear and the strip sander (used for sharpening) has a space in the middle, the rest has accumulated stuff. Build was documented in this thread. https://www.shopsmith.com/ss_forum/beginning-woodworking-f6/woodwork-bench-build-t12550.html
Building it was a good way to learn and practice using hand tools, It is easily taken apart should it need to be moved.
Last year he did a new series on building the bench from 2x4's,
