I was going to recommend you look at the Coachmen Catalina series....they have a couple bunkhouses but they don't appear to have one that meets your towing criteria.
They are stick/tin and wouldn't call them entry level but they are lower on the that scale. For the price point, I think they are a good bargain and fits our needs, usage and budget! We've been really happy with our 303RLS and it tows great...I do 60 and hardly notice being passed by trucks on the interstate. There have been only very minor issues (loose screws, etc) that I've taken care myself and hopefully we will continue to have "good luck" with the reliability!
Good luck in your search!
