We have a 60 inch sleeper bulit by Rhodes Rambler in Bowling Green KY,It is considered a low budget type sleeper but it does the job,there are 2 bunks plus plenty of storage space.Also the owner JIM is a extremely pleasnt man and if you ever need anything he will usually send it free.From what I hear I would stay away from Alum-Bunk,I hasve seen and hea5rd of terrible workmanship,lots of leaks and bad wiring that shorts out the truck.There is also a good sleeper oufit in Ft Worth Tx,and Benz in Ft Wayne IN builds sleepers,they can get pricy.Good luck.
