I have a x-160, not the wb, the regular 160. I love it! Nice and light, easy to pull with my Cherokee and plenty of sleeping space. We looked at other brand's of trailers this size and they did not offer nearly as much.

I was all hot to see an x160 until I stumbled across the floorplan of the x160wb. wb advantages I noticed are larger shower and ease of getting out of bed without disturbing your partner in the middle of the nite. Have yet to see one or talk with anyone who has one. wb is almost 2 feet longer than 160 but weighs slightly less if I remember right. Not much chance of seeing any fun finder in MT.
