Yes they do. You have to park over on the side were the semis and rv dump is though. The City of Scarborough won't allow overnight in the rest of the lot. You can't rv at the Scarborough Walmart at all.
No. They have cameras, and I tried once, the police came and told me to leave.
I think I recall a number of signs saying no, but whether the rule is actually enforced is not for certain.
It seems like they do. I've seen a lot of RVs parked on the far sides of the parking lot
