Having spent a lot of time in Portland, OR for business, I'd say you're crazy if you think the cost of living is cheaper. On the contrary, it's not. Housing alone is nearly twice as much as Ft. Worth, and Ft. Worth is one of the cheapest places you can live in the country, especially for that size. Cost of living calculators are showing it to be at least 25% higher overall, but especially in housing. If you make $30,000 a year in Ft. Worth you'll need to make almost $40,000 to enjoy the same lifestyle. Also, get ready for a state income tax. See the facts here. However, it is beautiful, especially during the fall, and if you want to live away from Portland you can find some nice land.
I'm interested in the RV470, though you mean an SV470 though, right? I'm in the DFW are and can pick it up. PM me a pic link.
