Hello, neighbors, it's Brad here from etrailer, and today on our 2026 Buick Envista, we're gonna be taking a look, and installing the Roadmaster Base Plate. Now this is gonna be the first step, and really gonna set the tone for the rest of mounting of components when flat towing your Envista, and this might be my personal favorite. Overall, this is a great-looking package when it's all installed. So let's take a closer look. Now when it comes to flat towing any car but our Envista today, there's gonna be five main components that are gonna be required. And the first one on the vehicle side is gonna be the base plate.
That's going to structurally mount to the frame of the vehicle, and create a safe place to be able to attach to and tow it down the road, and your tow bar is gonna be connecting to that base plate. That's the connection point between the towed vehicle and the hitch on the RV. Now, just like a trailer, you're gonna have safety cables that are gonna attach from the trailer hitch receiver on the RV to the base plate on your towed vehicle. Diode wiring is gonna transmit the light signals from the taillights on the towed vehicle via the seven-way, to a six-pole plug, and eventually to the taillights, giving you running lights, turn signals, and brake lights. In our case, we also had to use diode wiring to tap into our braking system.
Braking system is going to be the next thing that's gonna be required on all vehicles, and it's going to make sure that the vehicle stops and slows as you apply the brakes on the RV, but also this breakaway switch will make sure in case of a catastrophic disconnect, it would pull this cable, applying the brakes, and bringing it to a stop. Now on this vehicle specifically, it does require the battery to be disconnected, and there's a few different ways you can do that. Manual disconnects are fine, you can unhook the battery each time if you truly wanted to, but today we use the Roadmaster Battery Disconnect with a solenoid that's a push button, I would highly recommend doing that if you're gonna be flat towing quite often. Another thing you may wanna add onto your vehicle is gonna be a charge line, and that's gonna go into your diode wiring port at the six pole, and trickle charge your battery as you go down the road, that way when you get to the campsite, and you unhook everything, your battery is gonna be fully topped off and not having to jumpstart the vehicle. So the cool part with this base plate is it's gonna be nice and clean.
This lower kind of vent section allows those arms receptacles to be here, your safety chain loops are here, you have a mounting point for your six pull, as well as your breakaway switch, and that's something that I can't recommend enough is getting a base plate that has all of that. That way, you're not left trying to fabricate something up to make it work, this really makes it nice and easy. Now really any base plate, it does come down to the fact that you're pulling a fascia off for installation, but this one does a really, really good job, and it's totally worth the squeeze to get this nice, clean look. Now the great part about removable arms on a base plate like this is gonna be this is what it'll look like when normally driving. Pretty clean overall, and when you are ready to flat tow, you just grab your arms, put them in at a quarter turn, that'll snap in place, we'll get this other side, (equipment clanking) and then from here, we can hook everything up.
So something that I will point out today we're gonna be using a Roadmaster Nighthawk tow bar, and that's gonna have the Roadmaster pins, as well as the adapters to hook up to this, but if you have a different brand of tow bar, and you need it to hook up to this base plate, you're gonna wanna take a look at some adapters for the ends of your tow bar to mount up to this. You're not gonna be changing these arms out. So speaking of hooking up, let's take a look at what it takes to get this all set up. If you're a first timer hooking up a flat tow, it's actually pretty simple, and your base plate really sets the tone. I always tell people just go across, and theoretically everything should have a home, so first thing we'll do is get our arms in place, and this is why it's important to have the Roadmaster ends on your to
