Does anyone know if a 2014 LX 5470 have integrated trailer brake? If it does, I don't think I see anywhere in the vehicle shows that it does. What are some good wireless brake controllers?

There isn’t an integrated controller installed, but there is a plug to add one. Most people like the Redarc.

The wiring is all there, you just need to purchase each end. Rear end part is link above.

You can use RedArc like lx200inar mentioned or other brake controllers. There is thread in MUD how to open the dash area and where to plug the brake controller.

LX570 REDARC brake controller Install

Upgraded the 2019 LX570 with a brake controller. I have a little M416 trailer with an upgraded Dexter axle with electric brakes. Yes I know a bit of over kill. I added the Tow Pro Elite brake controller using the plug-play harness and the switch blank plug. Wicked easy the hardest part was...

Thank you for all the help! I'll check thread out.

Okay, so based on the manual, this is what I found. I want to know much weight I can put on the hitch in case I only want to install a cargo box instead of hauling a trailer.

The manual is being ultra conservative here based on what others have done and my own experience.

What it's stating is that with enough weight, AHC may not indicate "N" ride height. At a certain hydraulic pressure threshold based on load, it'll no longer be able to sustain a constant ride height and may reduce height essentially transferring more load to the coil spring system. Much like a normal car that will squat with load.

In practice, the thresholds are way higher. Depending on health of the vehicle and modifications, it'll be well over 1600-1800lbs payload before this is a factor. The system can be augmented for even higher loads. 2200lbs and still able to lift into high position.

The stated spec for the factory hitch is 500lbs, or 800lbs with proper WD applied. I'm at 1200lbs with my 8000lb travel trailer. I'm not condoning this, but the hitch is integrated into the furthest aft frame rail and is a beefy thing. 200-series cruisers are spec'd for weight, while still allowing ample margin for the intended HD use which may be towing over Australian corrugations in the Outback or abusive mining operations. I use the margin for more capacity.

Am I right in thinking that the weight at the hitch is calculated at the position of the ball while a cargo box would have a center of force much farther back?

Thank you so much for the insight, much appreciated!

Great point. How much further in cantilever matters because it magnifies torsional stress on the hitch, but it also increases weight on the rear axle.

To that last point, it's not just the weight carried on the hitch, but with more cantilever, it transfers weight off the front axle to the rear axle. With WD hitches, it can compensate somewhat.
