USAA will cover all mods as long as you have a pic of it on your jeep. Stolen, flipped, burned it doesn't matter they will cover it. If you have something that is no longer made they will get the next best thing. Also they always give you the newest model gear back. Doesn't matter if you put it on 10 years ago. They will pay for the new version.
Stare Farm has been great for me. Originally had Allstate and quickly found out not much is covered with them when it comes to aftermarket parts.
