Trading for the same size, you get all of the upgrades ETI has added over several years and all of the options and custom work you want that you did not get the first time. People new to trailering might not have known what they would use or want. All new parts and appliances, of course, as well, would be nice. Also in the event of a total loss, insurance would cover replacement with a new trailer of the year of loss, not just value of the old one.
Of course, most people want bigger for the bigger family or needed more space in the first one.
We never know if we might walk into a 21' and just have to have it. Or would get one as DD says because we can.
