I believe in 05 they were using a zemmin chassis/Frame. The units having problems were much bigger, FS3000 and FS3200. the 23 footers were not a issue. People have bent them on washboard roads when they did not unload their bars so that the trailer and truck could bounce freely. I.E. off road. Otherwise you'll be fine.
