When my last TT was totaled, I had put brand new tires on all the way around less than a year earlier. Rather than fight with my insurance company about the tires, I had the RV dealer where the TT was at for what I thought was service, remove the new tires and install 4 pieces of junk tires I got at a junk yard. I removed everything I had added on to the TT without stripping it of things like the fridge, a/c, microwave, etc., as those are standard. My insurance company did pay me for improvements I had made to the TT and was unable/unwilling to remove (I had to give them copies of receipts) such as an electric tongue jack, etc. If you don't have receipts for your add-ons or they were added more than a year ago, I would pull them and not say a word to your insurance company. My insurance company never even looked at my TT again once it was decided the coach would be totaled as the coach was going to auction to be parted out. The RV dealer had literally ripped the interior of the TT apart removing flooring to expose the mold damage and the TT was trashed so no one cared what I took or left. Probably could have stripped it down to nothing but did not.
