I need advice on my totalled yet still beautiful baby.

I went through an insurance company battle last summer, it took 7 months and reports from three different RV repair places to get my money. My claim was rejected 4 times before I was able to finally resolve it. Your single biggest mistake was not taking photos, without proof of the condition when it left your possession it will be a battle. I've started taking photos at the beginning and end of every season just to have a record on the off chance something happens again.
