Do they allow semi truck parking

I see them parked there

I believe so

I have seen many semi trucks parked at the far end of the parking lot near the cluster of stores to the left.(facing Walmart). Many for multiple days including weekends.

Semi trucks usually park at the far end of the parking lot. Near AT&T where most people never park.

I believe so. They are a short distance from Walmart, still in the parking lot.
