I am also having same issue as every else, out of stroke. Today pulled in to my spot, out of level front to back .4 and side to side .6. Hit auto level, out of stroke code. Retracted all jacks, hooked up jumper cable to truck as p25ct mentioned and system worked perfect. Not enough battery capacity for this system. At least I know I can hook it up to my truck and the system will work fine.
