I added an AS set after 16k noisy miles and have never looked back with the peace and quiet with better efficiency. Guess that means I need to do a fun loud trip soon...
Thank you! You still beat me to an answer even though I already bought it and haven't tested it. Prime Day sale was too good to pass up.
Was disappointed by how inaccurate it is at low tongue weight but I'll just have to stand on the tongue and do some math for light loads.
Honestly, as soon as these things start breaking out of warranty people will be scrambling for manual retrofits but ones that swap out for the motors not on top of the existing ones.
At least I'd happily consider that if it saves cash after 60k miles
