Parking options for Portland airport

Hey MP, I fly out of Portland next week and will need to leave my truck for 2-3 weeks. Does anyone have recommendations for fairly inexpensive long term parking?

Thank you. 

I've had good luck booking one night on either end in a hotel near the airport, which will allow you to park your car there the whole time you're gone.

- 10-11 a day.  probably cheaper than airport and more secure

I've had luck with airportparkingreservations.… flying in an out of Seattle.

Wow, thanks guys.
