I was going to stay at Indian Bread Rocks near Bowie, AZ for a couple of nights but saw the temps that were going to be there so pressed on for Tucson since it would at least be above freezing right now before heading to Quartzsite. Hanging here for a couple of days then onward west slowly...
I have stayed in hotel parking lots before but I always go to the front desk and ask for permission and all but once I have been given permission. I do take note of the person's name so if someone does knock on my door to question me I can let them know that I got permission and who gave it to me.
