For Sale EMS-PT30C by Progressive Industries
I have just the unit, no box and if I find it the little direction booklet. But all you really need to know is written right on the lid.
It's in very good condition, was used one season then we sold the previous trailer and upgraded to a hardwired one in the new 19.
$140 plus shipping.
