Mountain bike options for a tall guy

I’m looking to get into a mountain bike that will also handle paved trails decently. I’m 6’6”, so finding one that fits me has proven difficult as none of my local shops have XXL bikes in stock (from what I can tell, my height fits in the XXL category for most/all manufacturers). I’ve looked at Specialized Rockhoppers and Trek Marlins. I’ve also been checking Facebook Marketplace, but I’m not finding any XXLs there. I want to keep it around or under $1,000. Any advice is appreciated.
