That’s a 4-5 hour flight PDX to say, TOA. So you’d need 6 hours or so including IFR reserves to be on the safe side.
My Ovation 3 does that no problem and I have TKS. However, just to caution, there’s really no such thing as an all-weather bird. I have a son that lives in EUG and there’s been many days over the last couple of months that I’ve wanted to fly up to see him (from HND) but the weather is a NO-GO - Low IFR, icing etc. I’m guessing a K, Ovation, Bravo, Acclaim or a J will get the job done. I know Acclaim, Bravo, Ovation and K you can get wth TKS/FIKI, I’m not sure about the J variants. I’m assuming that you have plenty of flying experience and lots in IMC. If not, I would once again caution you to take it very slowly.
There are two types of TKS system - FIKI which is Flight Into Known Icing and Inadvertent which is, just that - for inadvertent icing encounters. Same basic system except FIKI needs a backup alternator and has a heated stall warning vane. I honestly don’t know anyone with FIKI that deliberately flies into known icing conditions. For me, the system is there so if I find myself in icing condition or feel like it may be on the way, I can turn the system on as I get the hell out of there ASAP.
By the way, I live and fly all over the Southwest and haven’t regretted not having a turbo. My 310HP Ovation performs flawlessly and can do it LOP.
If you want year round reliability of arriving at your destination on time, fly commercial. That said, Mooneys are magnificent aircraft and you will be thrilled no matter what model you end up with.
