Do they allow truck parking

It depends on what your question is?No overnight parking if that's the answer your looking for unless deliveries to the store .And asked the Head Manager. I hope this helps

Isn’t this the WM that boots trucks?

I've seen trucks parked there... Just not sure if just any trucks can park there.

At night, i always see 18 wheelers, however, I'm not sure if the drivers leave there trucks. It's mainly a rest stop at night.

Yes they do. There might be a time limit. Some Wal-Marts do.
