Hi Larry and Gerald,
   Alliance Coach tell me that Zantrex asked them to ship the failed new unit back to them and not to the supplier.  Zantrex have shipped a new replacement from California.
 To switch to Magnum would mean reversing the whole order;accounting for many hours labor already spent and questioning whethere Goods Sams ESP would cover another deal!!
   I am stuck with the Freedom ,but many thanks for the heads up.
