Supplies for your Toy Hauler/Trailer

Thanks for all the great replys! Fortunately for us my parents are leaving all of their supplies for us to have and get started. I heard from someone recently that a cordless drill comes in handy when lowering the stabilizing jacks so that is now on the list! My wife is handling all of the interior supplies so it is my task to handle all of the outside stuff, including tools/supplies for potential repairs. In the 6-7 years they owned the trailer we have camped with them a good 20 times so we are pretty familiar but always looking to improve the trips!
