We purchased back in Aug. (and to date have yet to take it out on it maiden voyage because there are repair requirements needed). It is Bighorn 3750FL with the front living space. Since Sep we have been working with Heartland and our dealer to have one of the two theater chairs replaced because the mechanical part was not functioning correctly. Well we heard by from or dealer today (12/30/2016) Heartland would not be able to replace the chair because the vendor Heartland used is no longer available. We have been told by our dealer Heartland wants to still replace it but it will not match the existing couches in the RV now. Since we are being forced to accept a substitute should Heartland not replace the couches as well since they will not match the color of the substitute theater chairs? It is disappointing, we purchased what is considered the 2nd best RV on the market and in less than 6 months we have obsolete hardware in this coach.
