Reproduction Steps

Open a "New Combat Vehicle" in MML 49.7. Default year is 3145. Go to Equipment tab, CTRL+click "Other" to view this exclusively and deactivate "Hide Unavailable". Some items are not visible in this view.

"Backhoe" item (and other industrial equipment with physical attacks such as Chainsaw, Dual Saw, etc) are available, but only when choosing "Show All", not "Other" or any other single category or manual combination of categories without actually hitting the "Show All" button.

"Combat Vehicle Chassis Mod [Environmental Sealing]" does not appear at all.
"Vehicular Sponson Turret" does not appear at all.

All other items from the "Other" category in 48.0 appear to be present, although some have changed categories (e.g. AMS is now under Ballistic, and Laser AMS is now under Energy) or had their names slightly adjusted.

Did some poking around and think it's a mix of flag issues on the equipment and the other filtering in MML. But not sure the best approach to fixing.
