Do they have overnight parking for truck drivers

I don't think so, but yet I see lot's of trucks

I've seen an area where trucks are parked, during day though not at night.

Bobtail ONLY

Yes

Bobtail only if you have the trailer most likely they will ask you to leave

Yes....in Laredo

Either way they let them park all day even overnight

I don't know, but I think they do because I see them like taking a break.

U would have to ask the Manger if u could . But sometimes we see some trucks there overnight.
