I’m not a local, so your suggestions are certainly better from a local perspective. Anything from Troutdale to south of Woodburn is a CF#$@& from my view.
Unfortunately, anything farther south or west of Gresham means that skipping The Dalles is no longer an option, which was an issue discussed
here. Kennewick to Wilsonville will be impossible when the Dalles is offline/overloaded (happens a lot). Of course Hood River will eventually alleviate some of these issues, but there will still be a high density of owners throughout the Portland metroplex, so additional well-placed local SCs will also be needed.
Personally I like Fred Meyer better than Target, but either one is better than none. How about Target at 21500 NE Halsey St, Fairview, OR? That’s near one of the Fred Meyer stores mentioned above. I also like Target at 9000 SE Sunnyside Rd, Clackamas, OR. Both seem good to me. Having V3s in both of those areas would seem to dramatically improve coverage. Throw in Wilsonville next is just more gravy. Maybe another email to Tesla is warranted.
