Wow, the truck looks like wasn't part of the accident, Im glad everyone is ok
Glad you two were unharmed.
If someone has no insurance what do you do? Small claims court? Or does you insurance go after her? Either way it sucks to hear. Hope you are able to get truck fixed cheaply.
At least it won't be your collision deductible. Uninsured motorist coverage dedt is usually less. Also, you are entitled to a rental while in the shop on an uninsured motorist claim even if you don't pay for it because you get treated as if you are a claimant. A receiver hitch can really save the damage on small hits, but a hit like this probably has more frame damage than if it wasn't there. The rule of thumb for the frame damage is it is repairable if no part is bent more than 90 degrees. Make sure to get a new hitch too! Bumper and bed will get removed and frame needs to be checked to be sure it is not diamond as well. Another first thing to check is for damage to rear of cab from bed contact. Good luck and glad you guys are OK.
Im not sure if the frame being bent rear of the rear tires is that big of a deal. Crappy thing is the truck is going to have an accident on its record so your resale value is toast.
I was rear-ended not long ago too; I was in my Nissan Titan and (like you) had my towing/hitch mounted..left a soccer ball sized hole in his front bumper (2002 Saturn), but I the Titan no visible damage. Guy was unemployed and uninsured as well..gave me an expired insurance card and begged to depart the scene before the cops came
