I used to live in Bisbee... just moved up here to Tucson... but I am so sad I left... anyway I used to see your little Smart parked with its little trailer... where do I get a trailer like yours?
Just wondering how you like Bisbee? My wife and I have been thinking about moving to Arizona for sometime now, and were not sure where to consider. We really enjoy Tucson, but kind of pricey. Another person told us to look at Douglas. Anyway, sorry to hear about the cold temps, but ours have been in the single digits as well.
Wix filters are very good equipment. They make many private label brands, NAPA filters being one of the biggest. I have used Wix and Napa for over 30 years with no filter related failures. Take the Wix number to any Napa dealer and they can interchange it for you.
