Hoping to give back a tiny bit as I've been using this forum for years and mostly lurking. I just completed a build of the Coastal Offroad bumper on a 2014 4Runner that I've owned since new. I did attempt to fit a 4th Gen PT228-89460 hitch in hopes of using a weight distributing hitch for better trailering at close to max rated (yes, outside of recommended use, but not with any intent of exceeding the vehicle's rated capacity). Short version - it does fit, would need an adaptor welded to bolt the center attachment points on, which would be extremely easy to accomplish. That said, I think the crossmember on the 4th gen is a tiny bit further back than on the 5th gen, so even though it bolts up easily, you can't use the stock spare tire location with it. I ended up canning that option, as I didn't want to go with a swingout yet. Ended up cutting a relief in the bottom of the bumper, reinforcing with some steel bar, and modifying the stock hitch to bolt on with the Coastal bumper. I'm happy with how it turned out. If you're just using a bike rack or other lightweight hitch accessories, just buy the Coastal hitch! I actually trailer, and wanted a stock hitch for that reason. Second mod - this bumper is designed to accept the Rigid lights. I wanted to use Baja Designs, for no good reason other than that I have them elsewhere in the vehicle. Ended up designing adaptors in CAD and having them laser-cut, then welding them in. I made a design error and some grinding was necessary, but the concept was successful. Finally, ended up failing to find anyone to powdercoat it (estimates were $1200 and 6 weeks) so used color-matched Smart liner (basically branded Raptor liner). It's not perfect, but it was cheap, easy, and should be durable. Happy to answer any questions about this setup!

I have many, many photos of the build, but apparently haven't posted enough to put them up here yet. Or maybe it's a limit per post. Not certain. Will just put the few I'm allowed up, and am happy to supply anything else anyone has questions on.

Turns out it's just a per-post limit. Figured I should illustrate another modification I made. They advise cutting the body mount bolts off to fix this interference - I'm OCD about checking torque on those intermittently, so opted to cut clearance holes for them.

And, lastly, I guess - I didn't want to use any filler on a bumper, so I reworked some welds until they were right, ground them with a 40-grit then 80-grit flap disc, then used medium and finally fine surface conditioning discs to get a smooth surface for finishing. Intent had been powdercoat but that is unobtainium for a shadetree mechanic in my area - the guys are busy already and just don't want the business. I primed with rattle cans, then used a Finishmaster branded version of Raptor Liner, tinted to match the vehicle color. It is extremely forgiving (first coat is what's shown here), though I recommend buying their pro gun rather than the basic Schutz gun for better texture control.

Wow, those are some skills!
That came out excellent!
Did you do any interior bracing inside the bumper?
Nope! There is some bracing already, at least bracing the rear upright sections in a fore/aft fashion. It should handle a swingout fine. That said. I actually stared at it for a while, and decided I wasn't comfortable with how close it is to the body metal, and the potential interference if I actually land on the bumper hard enough. Have decided to make some modifications...
