If you need to cut a bad section of wire out I would splice in a new piece of wire and use wire nuts tucked into a remodel box with a conventional outlet. It's still a continuous run, just goes thru the outlet.
Generally, when speed boxes have been used, there simply will not be enough wire loop to pull out, cut, insert into a workbox and then splice.. The wires are stapled in place and typically you get just enough slack to pull the outlet out of the wall and turn it slightly.
Been there, done that myself.
The through wiring of speed boxes means not only savings in speed during manufacturing but also wire. Yes, the wire savings may sound petty but if you save 1 ft per outlet and with say 20 outlets that is 20ft per unit and multiply that by 10,000 units built per yr.. 200,000 ft of wire the RV manufacturer did not have to buy..
14 ga Romex right now is running $.50 per ft..
That's a savings of $100,000 per yr for the RV manufacturer.
Second, RV walls are paper thin, standard 3.5" deep workboxes will stick out of the wall 2".. So, that requires low profile workboxes, standard low profile workboxes do not have sufficient cubic inches for a pair of Romex cables (in and out). Like this..

That leads us to using a special low profile workbox which has a "sidecar" on the side.. Like this..

But once again, if there is no slack loop in the wire, none of those boxes will work.
