By totaling the trailer, the insurance company is giving you a hint of the expense to repair it. The rule of thumb is that if the repair is more expensive than the value of a new vehicle (or trailer), it is cheaper for insurance to total it. It comes down to the ratio of repair cost to new purchase. Yes, the price has gone up, but your insurance company is telling you that repair will be as expensive, if not more so, than the original cost of that trailer.
