I would let management know first. I have parked a 26 foot truck before and they had no problem.
Be aware the police will roll up on you thou if you are looking suspect. I have seen people out there.
I've been living next to this Walmart for 3 years and I see RVs/Vans parked overnight all the time. They mostly park in front of the planet fitness next door though.
Yes they really don't trip on that
