I am new to the forum and have recently purchased a 1990 Ford E250 Quigly rigged extended camper van. It came with a "Polar cub" A/C heater unit. It runs on 120 Volts and is a roof mount model. It is NEW and never been used. Never been mounted.
COLEMAN POLAR CUB RV ROOF AIR CONDITIONER - $696.00
This is exactly what it looks like. I do not know the year it was made but can take pictures and send them by text to whoever is interested.
New $700 Asking price for new never used $500
Located in Northern Ohio and sorry but I will not ship...
