Just finished up running an AC vent to the aft cabin. Not too hard, just threw in a T box and some 4" tubing, cut some holes and done.
Also just finished hanging an LCD TV with digital decoder (broadcast) box, and HD antenna. The quality is really good for the 8 or 9 channels we get. Built in DVD player for when TV reception is bad.
Dropping the coax down into the aft cabin access and sealing wasn't too bad.
Relatively clean install except for having to run wire molding. Very tough to run wires behind the head along the gunwale.
