I recently installed a 2100XC in our Miramar. It had the washer/dryer prep already, which made it easier, but still had to drill the hole and install the vent in the side of the MH. Although this drilling of the vent hole seems daunting, just measure several times to make sure it is in the right spot and go for it! I would highly recommend the vented 2100XC over the non-vented 7100XC. We are very satisfied with the Splendid 2100XC. Installation was really very easy.
