Question:
Will I still be able to manually crank it if something happens to my truck battery? I don’t want to get stuck somewhere.

Hey Brian, completely fair concern - and yes you can, so you won’t be stuck.
The etrailer eclectic trailer jacks like 3,500lb # e72QV, 3,500lb with snappad # e22QV, and 5,000lb # e82QV include a manual emergency override. There’s a rubber cap on top of the jack head that you remove, and the included crank handle lets you manually raise or lower the jack if power isn’t available.
So even though these are powered by your truck’s 7-way during normal use, you still have a mechanical backup. They also feature weather-resistant rocker switches and an integrated LED courtesy light to make hookups easier in low-light conditions.
Brian, what type of trailer are you putting this on? That’ll help narrow down which capacity would suit you best.
