Hi Greg and Kris. We were over at Curtis trailers the other day (NO, not buying a new one) just killing time.
Checked out a Mountaineer with basically the same floor plan as the 3750. The differences were.....no outside door into the bathroom, and they had the arrangement you would like to do, with just two sofas on the slides, and a swivel recliner where the "L" part of the sofa would have been.
Any word on what's happening with your 3750 situation?
