I had looked at the VW EVs ( as well as pretty much every other EV sold in the US), and while a VW fan in general, I was disappointed in the range offerings of their EVs, so not too surprised with your experience. Range was probably the main thing I looked at when researching EVs.
As EV's go, the Silverado is one of the least efficient in miles/kWh, but overcomes that with its large size battery to get one of the best range offerings/$ even when towing, if you believe the YouTubers experiences . As mentioned earlier, I felt the range loss with age would still leave it in pretty good shape as we wind down our needs for range.
Frankly, I think BYD from China is so far ahead of the US manufacturers in terms of battery & charger technology, performance, comfort, and cost, that if the tariffs are ever removed the US car companies are going to be in really big trouble.
