How to figure my downtime after damages from receiver?

Hey y'all. Looking for some advice and opinions on a general situation. Say you were running a flatbed with a conestoga, and the load you go to drop is heavy and long steel. During the unload the forklift operator manages to get a piece from the far side hooked on his fork, which resulted in the beam slamming down on the rail that the conestoga wheels along when opening and closing. The rail is attached to the outside of the rubrail, and it was not only unusable for the opening / closing but it even tore two stake pockets at their welds as well.

This was in New England in the afternoon and by the time the plant maintenance guy and I cut and hammered the track to get it functional, I had enough time to make it to the one truck stop in the entire state (at least on I-95 anyway ) and grab a spot while they had maybe 6-7 open. The next day I go to 2 local shops to get estimates for the repairs. These were guys that the metal place sends their trailer work. Both were extremely nice places, and offered extremely similar responses- basically I was told that they would need a minimum of 2-3 days to get the parts shipped, which was Friday midday at the absolute minimum, and then the work would be a good 3+days or more. So I got the plant manager to see that point that I wasn't going to sit for the better part of two weeks waiting to get the repairs without compensation for the truck and my time.

Instead he agreed with me and the owner of my ride that it was a better idea to just deadhead to Pittsburgh and the factory where the conestoga was manufactured. It was basically a 525-550 mile trip and actually worked out better than I hoped. My boss called the manufacturer and they told him if I could get to Pittsburgh by noon the next day, they would get it done before close of business. This was a Wednesday mid afternoon so I ended up raising my anchor at 11:30 pm and setting sail. Pulled into the shop just before 10. I ended up dropping the trailer in one of their bays, and pulling across the lot to nap for a bit. Later waking up at about 2:00, light a smoke and get out to stretch my bones. As I was strolling that way, they were literally closing the back and tightening the straps on the back. All in all I was extremely impressed with not only their work and quality, but the guys in the shop all refused the several attempts I made to give a tip to all of them individually. Top notch shop.....

Anyway TLDR-
I'm trying to get an idea for what I should suggest the owner should ask for payment to the truck for downtime as well as payment for me. I'm normally paid a percentage of the loads and I am happy with the place. I don't want to be too greedy looking to my boss because I just started here this month, but on the other hand I have no qualms about asking for money for their accident. I'm not trying to shaft them either. What would you suggest that the driver pay for 2 days and about 800 miles be? What about the truck for wear and tear/being unable to earn plus fuel?
I know they will probably put up a stink no matter how low or high the charge we give them is, but aside from the averages of the past loads to get a # for lost revenue, should I just use the same method to get my past averages or somehow come up with something higher and how?

Fire away!
