New Toad

[TEO]

I just got a 2014 wrangler sport and next weekend im installing a Demco stay in play and a vehicle specific plug and play wiring harness for the taillights, along with a charge line. My owners manual says to disconnect the negative battery cable when towing. I believe that is to eliminate the possibility of a dead battery but with the charge line it shouldn't be an issue.
Online it also says I need a brake light relay to keep the brake light switch on the jeep from interfering with the function coming from the motorhome.
From the research I did it looks like I could just add a toggle switch to the cold side of the brake switch and accomplish the same thing, without adding a relay. Does this sound reasonable? I have to switch the braking system on to tow and off again so another switch would be easy to place next to the other one.
Sorry for the long post, any comments welcome.

I tow a 2018 Wrangler Sport with a 2019 Jayco Precept. I have a charge line to the Jeep and have never disconnected the battery nor have I ever had a battery go dead. I do not have a relay for the towed brake lights. They work just fine without. I also have a bicycle carrier on the Jeep that has park and brake lights. No problem with them either when being towed.

I haven't verified yet because the jeep isn't at my home but I think it's only a problem if the brake lights illuminate even when the key is off, and the braking system is actually pushing the brake pedal.
