Here's what a lot of folks who are not in insurance don't understand. It's not about the nature of the damage, it's about the acv of the vehicle versus the repair cost. Trucks hold their value very well. Your truck is probably worth 10k plus yet, maybe even more. Go on nada and check the retail value.
From what you described the frame damage sounds minor and is probably $1k or less to straighten. Frames can be straightened or replaced. It's very common. I bet your damages are no where near enough to total it. Just my .02. Good luck
