Mutt..I gave you my BEW and ZFW.
12200 ZFW - 9645 BEW = 2555 ZFW Payload
Based on last night winds..and some creative use of choosing certain power settings and the optimum alts....the trip was more then doable, considering all the places to stop between PDX and DAL....if the winds changed I probably would have stopped in Colo somewhere.
If your doing this on paper...shoot yourself now...your not going to be able to sit there, moving alts/power settings around to find and optimum combination that will keep you legal for take off, and have a legal reserve on the other end. Not in this lifetime that is.
