Border

....because this is an RVing in Mexico/Latin America Forum, of course any Canadian driving across the US for the purposes of RVing in Mexico (or, further south) will need a return service that will drive their rig(s) from Mexico border, into the US, to meet the Canadian owner (at say, an airport in Brownsville, El Paso, San Diego, Yuma).

But no ideas what the rules are in Mexico having a non owner of an RV rig driving said rig in Mexico TO the border crossing? Anyone? A Mexican notarized permission letter? The real owner's registration and insurance documents? A specific third driver insurance ?
