I like them. I first find out where level front to back is, then I drop the nose and deploy the rear electric jacks until they are snug. Then I raise the nose a little above level with the tongue Jack, then deploy the front jacks. Then I drop the tongue Jack down until it lifts off of the block. I set the front jacks down to the blocks, then lift the tongue Jack. Solid as a rock.
