Support for winter storage, jacks only or under TC?

When I store mine for the winter out in the barn I put 2 pallets sideways under it and let the jacks down just enough so a good amount of the weight is on the pallets. I was putting it all the way down but I keep it up now, keeps any critters from trying to get in and it makes it easier come spring to not have to wait to bring it up to load on the truck.
