Since buying the 4Runner last week, I've purchased a few things.
Lasfit mats for the front and second rows. Really good fit and coverage. More rubber than the rigid, plastic like WeatherTech liners we have in the wife's 4Runner.
Odero cargo mat. Covers 100% of the back, including the small areas behind the wheel wells. The WeatherTech we have in the other 4Runner is fine, but I think I'll like the total coverage of the Odero.
Also added the panels for the back of the second row. Should provide protection when those seats are laid down. Since I didn't get the same mats for the front and rear, I had to find some that were sold separately. Found these at 4Runner Lifestyle.
Finally got some smartphone door inserts, which allows for keeping the phone, wallet, flashlight, etc. In the door below the handle. Without these the space is not ask that useful as the lip isn't yak enough to keep things from falling out.
The inserts are fairly solid and affix with double-sided tape. Also from 4Runner Lifestyle.
I bought an Offroam phone mount that is engineered specifically for 4Runner. Solid construction and firmly holds the phone. Not sure if I'm going to keep it though. With android auto, I don't really need the phone in front of me.
Thought I'd post on case anyone is looking at getting some new accessories.
