I just purchased an 18' enclosed cargo trailer with double leaf spring axles. It will be parked in storage for an extended period of time. To avoid getting flat spots on the tires I am going to jack the trailer up onto jackstands during the time it is parked.

I checked the owner's manual that came with the trailer but it surprisingly doesn't mention anything about lifting or jacking the trailer.

Where should I place the jack?
AND
Where should I place the jackstands?


Thanks!
