I replaced my older Concertone with this one off of ebay. I have had it for six months and we use it all day every day.
Very good features and very good sound. Granted I also changed out my cheap concertone speakers too with Kickers.
Really has a lot of nice features and options including 5.1 surround.
There are two models depending on which opening you have...if you have a concertone then most fit the larger opening.
The only thing it does not have is Blue Ray but I have never seen an RV unit with it. Seems like you have to go to a home style setup and I do not have the room.
I was a bit iffy at first but had good reviews and after six months of almost nonstop use....no issues.
Really has very good sound especially if you have or add a powered subwoofer and good speakers.
Wish the stupids at Forrest River wired the four ceiling speakers for surround instead of just tying them together in the ceiling into one zone...would have made wiring them for true surround possible but sadly Forrest Rivers wiring sucks....really pathetic work.
Anyway...a very nice looking and operating unit...has all the inputs you need as as well as 2 HDMI.
Not going to get into which unit is best..they are all made in China so mute point but atleast this one does not have the horrid failures that the stock ones have.
I looked for 4 months at EVERY model available..spent hours googling. One thing that may affect what you choose is the opening and how much space there is to modify. See I could not go to a car head unit as the space was wrong. My older ckts has the opening and no extra room width or height so needed a direct sized replacement. Your space may differ.
There is another RV system you missed but can't find the link.
Thats my experience...yours may be differ as may others.
