I have the 2012 28' Intl Signature and my speakers are placed as you described. I am not sure why one model is setup like mine and the Serenity has them in the BR. I can tell you after a year plus now that the placement in my trailer is fine. I'm not sure I would want them in the bedroom, as when I'm in there I'm generally in bed watching the TV (an option I highly recommend, BTW). It's possible to route the sound of the main TV through the other speakers (but not the BR TV). Eventually, I'll replace the factory jobs (cheap) with some decent models, but the sound from either the CD/Ipod/radio, etc., is more than adequate....not for the 1812 Overture, but from the basic music/commentary standpoint. You will thoroughly enjoy your 28. The floor plan works really well for me. The only thing I don't particularly love is the L shape sofa. It looks nice, but it is not all that comfortable due to its height and width. (My two basset hounds do like it, and the UltraLeather seems to be basset-proof.) I may eventually pull it out and put in a couple of nice recliners. I've done a number of upgrades based on what I've read on these Forum threads. 16" wheels/tires, better converter/charger unit, designer draperies/spread, window boxes, etc. It tows like a dream and I look forward to MANY years of enjoyment. Congratulations on your purchase!
