I have a 2020 24D.
You can improve the stereo sound considerably by disconnecting the center speaker (one of the two plugs - I think the one closest to the windshield). This will give your door speakers a chance to be heard and adjusting the balance will actually work and won’t affect the emergency system). A guy on the Sprinter Source website actually cut the wire on the windshield side plug and inserted a potentiometer so he could control the volume of the center speaker and reported a very satisfactory result. I am considering doing this, but the View doesn’t have the same blank button slot that he used (the View has the stabilizer alarm light and speaker installed there), so I’d have to plan a different solution for the knob.
I’m loving the way the chassis handles, but am coming from a class A gasser.
Also have the lithium Batteries. No issues so far. They have handled the fridge without issue with the solar panels more than keeping up in a driveway test. I don’t usually boondock, so your experience may be different.
No issues with GPS, but I like the Apple CarPlay option. The height at 12 feet, has not been even a close issue so far. I have found even the “RV friendly” GPS systems can throw you a curve sometimes. It’s a lot less of an issue with the smaller (for me) View.
The wife and I love it. We’re adapting to a smaller living area without a problem. I did install a Bose sound bar below the TV to give a bit better sound at volume. I do miss the surround sound system of our class A, but the Bose gets me pretty close.
