Huge Rear Axle On My TRD Off-Road Trim - 9.5" Upgrade | 4th Gen Tacoma Forum

I am clearly showing my age with this one.....and it might seem to be a frivolous thing, but I genuinely want to know if I'm the only one out there that hates having the cargo in their bed sliding all over place and banging into the sidewalls and tailgate. The old school rubber bed mats, in my opinion, should have come with the floor mats for the Tacoma. An absolute must have have given the "slick" composite material that makes up the bed of the Tacoma. I got this one from TrailFx as its a bit thicker than the OEM Toyota version and less expensive. Does anyone else care about this like I do?

For those wondering, Toyota did give us a lot of what we asked for in this new truck. One crazy important feature, the 9.5" rear axle. This axle is nearly as big as a Dana 60, only .25" smaller. Naturally, they are super strong. You could technically run a 40" tire with relatively little issues. My plan is to run 37s bare minimum in the next few months, and 40s only if I decide to throw it on portals. But I'm beyond stoked on the beefier rear end. Hopefully the front can keep up! The 3rd Gen had a max size of 8.75". While still a good size, these new ones are much better.
