One option might be to contact an RV Dealer either near where your trailer currently is, or near your home and see if they can arrange transport. The Dealer themselves may be equipped if they do pickups/delivery on their own.
Another option, depending on financial ability, is to find a suitable used truck and purchase it. Remove the hitch from your damaged vehicle, install in the newly purchased truck, haul trailer home, and then sell the extra truck (less the hitch).
Depending on purchase price, which can often be a great deal compared to what you'd pay at home, you might even break even.
Remember for a one-way trip it doesn't need to be anything fancy. Just what you need to get the job done.
Since this was a hypothetical question, I hope you never have the need to do this.
