A good thing about the auction sites is they show an actual sale price.

To get top value, you will have to show examples that are equivalent to your truck. A couple years ago, my enclosed car hauler trailer got wiped out in a hailstorm. No structural damage, but totaled due to cosmetic damage. I had to fight with State Farm for four months because they kept trying to value my trailer by comparing it to the cheapest stuff on the market, when it had a finished interior and many options and upgrades. I finally got what I wanted for it, but it was a fight, and I had to provide comps for the value to prove my point.

Buying back at salvage is also an option, but you have to consider that the truck will always be devalued by a branded title and balance that with the cost of repairs. I bought my trailer back, and continue to use it to this day... it looks like a golf ball, but it still functions 100%. It was a no-brainer, because the only actual repair was a $100 roof vent.
