Since 1988 when we started with Starcraft Meteor (8' box). A year later, traded in for Starflyer (10' box). Two years later, traded in for Starstream (12' box) which we kept for 10 years. Then, a Sunline TR280 that we had for 10 years. In the fall of 2013, we bought our Minnie, and we plan to keep it for as long as we can keep camping and traveling with a TT. If it becomes a problem, we would look at other options!
