Sorry to hear about the water leak in your new rig, unfortunately in the RV industry brand name does not mean much since they are all hastily thrown together. A quick search online indicates all RV manufacturers are prone to building issue laden rigs, some are glaringly obvious, others remain hidden under casual usage. Hopefully it is a simple fix, maybe a fitting that is not quite tight enough, although having water getting all the way to your entertainment center would certainly be alarming to say the least.
Been RVing for over a couple of decades and have learned to do the repairs and maintenance myself, that way I can ensure it is done properly and expeditiously. Thankfully our entry level rigs have only had very minor issues and have never been back to the dealer, although the dealer did provide the parts required when still under warranty. Brand name is about 5th on my list when shopping RVs, floor plan, cargo carrying capacity, dealer service reputation, and manufacturer's compliance with resolving warranty issues lead our list.
