Ground control (electric) jacks seem to have less travel than the level up (hydraulic) ones. Putting blocks under the tires increases the length needed for the rear jacks to contact the ground and you may see “failure” more often. No need for blocks or anything under the tires, and jack failure is extremely rare.
