I own a 2012 305sk. After a couple proplems at first, that you can probably find on the forum , I have had very good luck. I work out of town and live in my unit for months at a time. In all kinds of weather. My unit does not have schenteck slides. You read about alot of bad things on the forum, but I am more than pleased with my unit.
