Bill and Mary: We also have a 3670 Big Sky. We agree with the comments from tbhd. It is almost as if we wrote what he said. We travel with our adult son all the time. We are currently spending 6 mos. in our unit in Texas and find the unit just perfect for a long term stay. As Stiles noted the ability to control the slides individually comes in handy at Flying J's or Walmarts when we stop and can get beside the grass.
We have a 2500HD GMC with the Duramax.
