I understand your concern, long story short, my brother drove my dads truck and rear ended someone. Water pump and other things had to be replaced. We had nothing but problems with that truck afterwards. They got rid of that truck after constant repairs. Recently my dad was sideswiped, almost like an angled t-bone really. Tweaked the frame and of course body damage. After it was repaired he had no problems with it and said it rode better.
Honestly if comes down to the luck sometimes. Just makes sure you use a highly rated repair shop that is recommended by the insurance company, either yours or theirs, and grill the repair shop with questions. Like if they use aftermarket parts or oem parts. What is their warranty like and such.
Make the other guys insurance take care of your rental. You shouldn’t have to pay for that since it wasn’t like you were looking to be rear ended or anything. And as for the depreciation on your truck, it might not be as bad. The way the new/used car market is now it might not have affected it much. Believe it or not, after only having my truck for five days I was rear ended. Low speed impact, $3k in damage and labor. Just for fun we looked at the value of my truck, even with the accident, I can sale my truck for a profit.
Sorry for the long post, anyway good luck with the repairs and let’s us know what’s happens.
