ok getting closer to buying my 1st expedite straight truck,have looked at many. all kinds of diffront sleepers,motors,sizes,transmissions,axles,box size,class 8,7, on and on ,then i came across this fraightliner fl70 with a 28' box with the sleeping quarters in the box.very nice set up low mile, priced right ,heat and air,insulated,tv, refridge,ect. it takes 5' of the box that leaves 23' for cargo. this could be a very comfortable set up nicer than factory sleepers.not sure of the curb weight and hauling cap.wt. but my questions are,could this be a dot approved sleeper. and will carriers hire a truck like this?
