First test run. You'll notice the ready brake cable is missing, this was installed before departure.
Ready brake cable on the LX side. Decided to use the license plate for a mount. It doesn't really bear any load and there is a clamp and bracket behind my license plate as well that stabilize the cable. The zip ties are just to snug up the plate so it does not vibrate.
What the system looks like inside the cabin. It's super simple. Just a surge brake that yanks on an aircraft cable inside an aluminum sleeve and pulls the brake pedal. The spot I drilled pops out just inside the drivers side fender well. I have it routed along the top of the fender well then it arcs down in front of the front body mount and curves up into the bumper and out the license plate.
The install was super easy. This part took about an hour taking my time and making sure everything worked properly. I sat in the LX while the RV was towed across a parking lot to ensure the brake was engaging properly and not dragging when not braking. There is also an LED with a very long harness that comes with the kit that you can mount on the dash of the towing vehicle (RV). This seems a bit useless to me as it's just actuate by the surge brake lever on the tow bar. It's not telling me anything about whether I am adjusted properly and actuating the brakes in the toad. And if I lose brake in the toad... well it's still going to light up and tell me I am braking. I kept it for now but left it uninstalled. I am guessing this is perhaps more of an inspection requirement for some areas vs something of actual use?
At just over 1,000 miles towed 4 down now. Drove the LX about 40 miles today and even hit a little trail and crawled around in low range. Still no issues. I am disconnected the LX and driving it around in High and Low range at every stop. So far the longest leg it has gone without being driven under its own power is about 400 miles.
I am in no way advocating that this is safe to do and you won't hurt your vehicle, just trying to share my findings. Maybe in a year when I have tens of thousands of miles towed I'll preach that the LX570 is a fantastic flat tow vehicle but until then I'd watch this thread. I'll post more as I go.
Next stop I am working on the lights. Due to the nature of the ready brake system I have brake lights without any electrical work, which is great. But no turn signals on the LX when in tow. I am going to first attempt to power the 7Pin connector on the LX directly and see if it lights up the indicator lamps as that would be dead simple. If that does not work I am going to just drill into the housings and add an extra bulb on each side that will be wired up to the front and plugged into the 7Pin on the RV when it tow. Either way will be pretty easy. The Blue Ox tow plate came with a nice bracket to mount a plug on the front.
