overnighting options - Mazatlan - Durango/Torreon/Saltillo

Thank you Tequila. This is what i'm looking for. Thanks for the update. I did see your earlier post when i was researching last fall. Hundreds of RV's must have used this route so far, but few posts of how they managed to overnight safely. Free overnighting in a Pemex or Walmart is always my last choice when for a few bucks there are decent, safe, options.
