installed a 9200 coleman yesterday on my 08 Northstar. Thought it was prewired, after cutting the 14X14 hole in the roof discovered an empty 1/2 inch plastic tube running towards the drivers side in the approximatley 1 inch thick styroform ceiling. Took me about 2 hrs to get the 12 gauge electrical wire snaked down to the converter. The install went very well after the wiring was completed. Ordered a westinghouse WH2400 generator from Amazon this morning. Reviews of it indicated it should run the coleman. I wonder about the life span of that generator, time will tell.
