I have seen/read good things about the Northwoods units, but have not personally seen one to really see the construction first hand. The DW really likes the size and layout of the 27-5L they make. We both want a fifth wheel for the towing benfits, but hate how big most of the fifth wheel on the market are...
Sorry long rambling... The Silver Fox 35-5Z might be one layout close to what you are looking for, but not many dealers around so might make for a long trip just to see one.
