We have a 2008 Big Country 2950RK that was purchased this last Sept. 07'. Several of the annoyances (I stress the word annoying) that we would like to upgrade i.e. winterization valving/location, stereo/surround system and exterior speakers all seem to be taken care of with current 2008 models. Will the factory provide any assistance on the upgrades to our 2008 model FW?
