And thanks to all who answered!
Unfortunately, I am all too knowledgeable related to the tail light issue you are experiencing. To convey the least this is a "planned and support design flaw by Forest River Leadership". I was on the telephone with the person in charge of this area today, and the person tried to defend the fatal flaw of the design (you can not make this stuff up!).
I will buy you a beer of your choice if this is not your problem. Just under the driver side rear of the coach attached to the bumper (actually a plate connected to the bumper is a "Curt Power Circuit Protected Trailer Converter". This unit, per the manufacturer specification, must be mounted inside and outside the exposure to weather. When you see it, you will immediately conclude that it could not of been more inappropriately mounted to void the product warranty. To make things worse, the wiring in this area looked like it was done by a kindergardener learning how to use scissors for the first time...I kid you not.
On our maiden trip (today makes 2 weeks ownership of our 2401W MBS), we had this same problem....and then some with our lights. Neither the dealer that sold us our unit or FR were of any assistance. They both suggested it was an MBS problem. So we spent a half day with MB....although they knew immediately it was not their issue because of the modification of the lights to make the coach, they went the distance to try and assist.....to include taking a new dashboard switch out of a new unit on the lot to prove it was not on their side. Then they were willing to speak with Forest River to cover over the wiring diagram.....the person we spoke with conveyed they did not have one....
Long story short, after speaking with (literally) an unknown number of dealers over numerous states to look at the problem (at this time all of our running and marker lights would not turn on)...we finally got a referral to a non-Forest River RV shop (by an employee who shared he was risking his job by making such a referral)....they immediately diagnosed the problem and fixed it (or at least all is currently working).
