You can level the head by using both jack screws, tilt side to side by using one, the head will self align side to side and has never been a problem for us.🤓
Back slowly until the shank is an inch or so in the head, get out and look, make sure the AS wheels are chocked, put in reverse, on level ground I don't even have to give it gas, usually seats in no problem.👍
