Super destructive chewing

I’m out of things to try. My dogs daily schedule, wake up, go outside for bathroom, unleashed(we live in the woods in the Rockies mountains with no fence), eat breakfast, she goes back to bed, I get ready for work, she goes into her crate and I leave, I come home at lunch to take her out again, she eats a smaller lunch, back in the crate when I leave, I get home and put her in the car, we go to a big wooded area and I do about a 1 mile loop, she does a lot more as she freely runs around, I’ll work on recall training while she runs around, we get back and mill around the house until bed.

Issue is, she chews on everything. When she was a puppy she would chew on walls and trim, even doors, she ate shoes, pillows, table legs, chairs, books, blankets. Now that she’s grown a bit(1.5yr)she sticks to soft things, blankets, pillows, couch cushions. She used to do it before she was kennel trained anytime I left the house, now that she’s grown is kennel trained she does it anytime I don’t have a direct line of sight, i.e. I step outside, I use the bathroom, I leave the room in general. She has plenty of toys, only the bamboo ones though, she can destroy a ball in less than ten minutes and any fabric toy no matter how indestructible they claim to be she has the stuffing out in less than an hour. She doesn’t even chew on them like regular dogs, she finds a seam and grinds it until it’s cut, then uses her front teeth to pull it apart. It’s wild, kongs last the longest at a couple hours but then theyre turned to little chunks.

I’ve tried everything I’ve read online. We tried puzzle toys, she broke them on the first use. We tried the treat in a kong, she chewed the Kong apart, the sniff pad was ribbons within minutes. We go on an hour hike everyday, we work on training. But she only seems to like that if there are treats involved, first time she doesn’t get a treat reward for something she stops doing it.

I’m really just looking for some guidance that doesn’t just say oh she needs exercise or mental stimulation, I am aware of that and I am running out of ways to do that. I’ve raised and had many dogs in my thirty some years but I’ve never had a dog behave like this, I’m stumped and everyone I ask is stumped so any help or advice would be helpful.
