No, it's a hot wired 12v line from the front of the underside of the trailer. Should be on the A-frame right behind the front cross member with other breakers (next to where you 7-way trailer plug goes into a terminal box). They omitted the breaker and wired the fridge to the 12v DC source where there should be a 15 amp mini-breaker of the auto reset type (they ommited the DC breaker). See the PDF below of the dealer service sheet that has additional info and directions and illustration on what needs to be done:
Note: I'm pretty sure the notices only get mailed to the original owner, so any subsequent owner may not receive one, but this is a NHSTA Safety Recall, so it should not matter if you are the original or the 20th owner, if it's an affected unit, they should fix it as per the recall sheets.
I will add this also. It is not unheard of for a problem that is the subject of a recall to also apply to other years and models in small numbers. Especially if those units were made at the same assembly plant. There have been more than one recall that was initially for x year and model that expanded in a later update.
