You might as well have a heads up that because your Jeep is modified the insurance adjuster is going to attempt to rape you on the value of your jeep. They will tell you because its lifted and modified its worth less than what it would be worth if it wasn't modified...
when i rolled my 95 in 2001 it was 6 years old with just under 100k. they gave me 5150 for it and let me keep it, told me that they would've given me an extra 1k if it wasn't "modified"...and it took them a week to figure that out...(those prices were after the $500 buyback)...
Good luck...try telling them that all those modifications probably saved them medical bills...but doubt that goes very far...also if you have any aches, pains, hurts beyond what is normal and you think you might need to get checked out, get checked out, don't try to be a man and ignore it because the longer you wait the less likely insurance is going to pay any medical bills...
***edit i see you did go to the ER***
