Love these units!  This I bought for my rv - perfect for this use.  I work in property management and this is the only model that works exceptionally well with a digital thermostat, mounts on the wall and is reasonably priced.  (Tenants run off with the free standing models).  Extremely easy to mount and simple to operate - simply hang, set your temperature and walk away.  If for some reason the thermostat seems off for your needs, it can be recalibrated (although it is a bit tricky).  Love the new dark color as past models were always white.  Downside is that the remote is cheesy and inefficient so we don't use them, nor are they needed...
