@inthehands @harpaa01 Congratulations! I hope you continue to love it as much as it seems like you do now. I certainly have - I'm about 1.5 years into a GSD (we're a single-car family with two kids) and I still adore it.
I'd offer to be a resource but I think your choice of the belt drive addresses my only serious caution about the GSD, which is that mine chews through chains and rear cassettes.
I did learn to change my own disc brakes b/c of it and highly recommend. It's not too bad.
