Huh. We have a 2021 and I'm pretty easily annoyed by crappy AV equipment, but LOVE the setup in ours. Sure, the components could be higher end, but the 1080p TCL Roku is great (wireless display, so can use as second monitor for laptop) and love the app (I never say that, and it took me a while to figure out it was the key to BT sound output), muting the speaker and streaming the audio through my phone to BT headphones, so I can have background on while working and not disturb my wife. It was odd they didn't put in a $2 wire to connect the headphone jack on the TV to the RCA jacks for AUX2 on the back of the Jensen DVD head unit, but four screws and done. The Jensen has BT input, too, so anything you want from your phone through the speakers. Outside speakers aren't overwhelming, but I'm not one to force my musical tastes on my neighbors, so adequate. Inside speakers are fine, too.
The only thing that's a bit annoying in the trailer OEM features (other than the crappy Chinese tires that ripped up my skirt, and the dumb use of PEX fittings to join PEX to hose in the plumbing) is the thermostat sensor being in the Furrion AC. Even the relocation kit use doesn't fix the weird triggering of the furnace. Otherwise, golden!
