Just FYI, but some protection for the AC condenser might be a good idea. Otherwise a rock/debris kicked up by traffic, or a stick, could take it out and cause a loss of freon.
Lov'n the high clearance rear departure angle for your back bumper!
One of the things I really dislike about the MetalTech rear bumpers. But on the plus side of MetalTech rear bumpers, is that it makes a great platform to stand on, prepare food, work on, a seat, etc. which we use all the time. It sticks out about 6 to 9 inches!
With the winch mounted that high, a pull would expert a substantial amount of leverage on the bumper itself and the front frame horns. Most winches are mounted quite a bit lower - in line with the frame horns - which reduces leverage (i.e., moment) on the frame horns during a pull. I'd estimate that the high-mounted winch could apply about double the force to the frame horns compared a more conventionally-mounted winch (measurements would be needed to verify that estimate), with the moment (i.e., downward twisting force) component of the loading probably being well beyond what the frame horns were designed for (they are only small 1/8" steel tubing, after all).
I would suggest a set of frame stiffening brackets to keep the frame horns from getting damaged. I have them on my bumper, where the winch is mounted basically in-line with the frame horns (see photos of mine below, which are from SRQ Fabrications). They tie the bumper and frame horns into the core support and sway bar mounts, which distributes winching load over a much larger area. They might not work on a KDSS-equipped GX460; you may need to find another supplier who offers them for KDSS-equipped rigs (or have a set fabricated).
A better comparison would be Peridot, Nori, Sage, and Cypress green all next to each other . TBH I like all of them despite being a Cypress green owner.
I drove my GX to work today which was the first time I have driven it in a month since I got the Honda Fit "beater", I use quotation marks because I actually really enjoy driving it and for a $2800 car it's damn nice... still, quite pleasant to get back in the GX
