Used market for higher milage 4runners

So I'm in the market for a 5th gen 4runner, coming from a fully built Tacoma, and moderately build 100series Land Cruiser. I purchased my cruiser with over 200k miles. How's the longevity of the 4Runner? I've been trolling the forum for the past month or so but haven't come across a ton of information discussing high mileage vehicles. What are some things I should be on the look out for? Are there any problem areas to be aware of on these vehicles?
Any information would be greatly appreciated!

 

Our 2004 had 144,000 before it had frame rust issues. That was in 2016

 

Haha, I'm well versed in Toyota rust issues especially after having my 2010 tacoma, I flew down to Florida to pick up a rust-free 100 Series. I wasn't sure about the rust on 5th gens, I'm basically looking for 2014-17 which seem to be in my price range depending on miles.

 

Hertz rental car is selling a lot of 2016-2019 SR5's with 40-70K miles for good prices.....if you want a former rental?
