I have 2 of their trailers.  The oldest one (first picture is a 99 model).  The newer one is an 04.  The 99 is a spring suspension and the 04 is an air ride.  They are good trailers.  They have excellent hopper clearance.  We can load 1100 bushel of corn on a 36' trailer.  They are good people to deal with and they stand behind their trailers.  There are at least 10-12 Drake trailers running right in my immediate area.
