Yes
I have seen RVs park there. We have an RV, but live close to there. I have stayed in Walmart parking before. It is always good to let them know or ask if being there is ok.
Don't know I don't have an RV.
As far as RV facilities (toilet download, water pumps etc) I dont think so, but you can park there.
No place 4 semi parking. Hope that helps
