Modify front seats to recline further?

I was wondering if anyone has modified the front seats, specifically the passenger side, to recline further?

I’ve seen a few Tacoma owners have done it.

I would like to get the seat back as horizontal as possible to place a sleeping platform over it for camping.

I have a 13 CrewMax but I’m too tall to get comfortable sleeping across the rear seat when it’s folded down.

I don’t really want to get a bed tent or a topper. I like the idea of sleeping in the cab for security reasons and sound damping.

Plus it makes leaving the next morning a lot simpler and quicker.
