Does this walmart have truck parking

YES

Everytime I've been to any Walmart, I have seen big trucks parked. To stay any length of time u would have to get permission from the store manager.

There are no specific spots for you to park but the parking lot is big enough for you to fit a big rig.

yes it does

Yes it has

If you mean big rigs then the parking lot is definitely big enough for you to park it on the lot
