We have the Coachman version of that trailer and are pretty happy with it. I understand your concern with the bed / door location, but honestly it hasnt been an issue in the places we have been. Mainly state parks. Before you put in anything permanent I would suggest trying some kind of tension rod and curtain setup. I suspect trying to move around it will cause more issues than its worth.
