RV tech authority Mark Expert of RV Education 101 has taken on the big project of producing a weekly half-hour online TV show about RVing. It might be the most interesting feature show about RVing today -- on TV or on the Web. We don't know how long Mark can keep this up because it's a huge, time-consuming effort but we do know that what he has done so far is outstanding. In this episode Mark and his son Tyler continue with their restoration of an old Yellowstone travel trailer. And Mark has some other helpful tips about using and caring for an RV. Good stuff.
