There’s a lot to unpack in this issue, but it frustrates me that there has been such effective opposition to providing wiring and circuits to support possible future electric appliances and EVs. I can argue for either side of restricting gas appliances, but as the article notes the electrical upgrades would be trivial additions to the cost of new construction or significant costs if added later. If you choose not to use the 240V circuit for a range, dryer, water heater, or EV charger… just don’t use it and it doesn’t hurt you

It would shed rain off the low end? Can you use a gutter and downspout?

Any reason the high side of the shed roof can’t intercept the existing garage roof further up the pitch? Then you could use open web trusses which although deeper are lighter and potentially cheaper than a wide flange. Attaching them higher also gives you more clear height with a longer span.

Kobo + Calibre is pretty easy, and the device itself is very nice.
