does anyone have any idea where to park a pickup and trailer in phoeinx area  if a person trailers it and wants unload and ride for a week?

Check out truck stops in the area.

I have some luck talking to the Manager of the local Harley shop well in advance of arriving in that town

I don't know. I never trailer my bike.

Can't ride in nebr in feb

HD dealers are usually helpful or try Self storage lots< They might charge you twenty or thirty dollars for a week and are fenced in for security.
