Rear end hit, frame damage - how bad?

This tundra is a 2010, apparently the accident was 6+years ago. Truck is aligned every year and has no driveability issues. My thoughts are this is just a towing/trailer braking risk, as well as rear collision risk. I originally considering leaving it unrepaired but never towing over 2,000lbs...

I know this is a fairly common problem with rear collisions, I'd love to hear from anyone with experience either fixing or leaving the frame as is...

Last pic is other side, also has a smaller bend too
Other side also has slight kink as well

 

Slight bed hump too

 

Well that’s not helping anything by being bent like that. But with where it is a frame shop should be able to straighten it out for less that $1000

 

Get it fixed.

Consider if you were in a second accident. Do you want a solid frame or one with pre-crumpled zone?

 

I'm with you guys. I'm pretty sure I can get it fixed (maybe not 100pct cosmetically) and then not have to worry about it! Now to get some quotes...

 

Can it be straightened and then maybe boxed in a bit or double up on the metal to keep it strong?

 

My guess is that it's designed to be crumple zone from the factory so when in an accident it bends to soften the blow to the people in the cab. I can be straightened with a frame machine. I wouldn't beef it up as you could make it too strong. I would also replace the bumper mounts as they are most likely bent as well.
