Question:

Is the RM-156-25 kit protected through the relay against voltage feed-back to the motorhome? I will be installing it and also installing Demco DM86RV! Thanks

Yes, the relay that comes with the Battery Charge Line Kit # RM-156-25 is designed to protect against any voltage from your 2021 Ford Ranger backfeeding to your motorhome.

The Demco Stay-IN-Play DUO # DM86VR is an excellent system for flat towing. It's easy to setup (after the initial installation) and it stays out of the way when you're normally driving your Ranger.

I've linked installation videos of both kits on a 2021 Ford Ranger for you to check out.

For a complete flat towing setup you will need a base plate kit, tow bar, safety cables, vehicle tow bar wiring, a supplemental braking system, and possibly a high-low adapter. If you do not have all of these components just let me know and I can make some additional recommendations for you.
