Started looking for new tires for the rig so we can get home Thursday.  Contacted Orange Tire to see if they can deliver and change here at the site.  No response yet, so I expect it will be Monday before they respond.  Having a good time, and if all else fails we will try to make it home with the tires we have.  I just don't trust them.  We'll be ok.  I think we are really going to enjoy this travel thing! :)
