As you suggest, Lee, it will firm up when the sheeting goes on the rafters.
Couple of points your dad might consider. Put diagonal braces (say 4x2)
from the top of the outside posts to the bottom of the centre posts.
Include short (2 foot) 45 degree braces at the top of the posts from the
post to the longitudinal bearer (probably not the right term). I built two
similar structures over the past winters for storing plant. The only
differences were roofs sloping from front to back and hit and miss boarding
on the sides. 4x4s provide the support and they've done fine.
