I can vouch for the sway deal on v-nose trailers. I just drove 12 hours with one (See personal page).. although Mine is just under 11 ft tall. I didn't have the load equalizer hooked up. (In shop right now having it installed) I am hoping that it fixes the problem. They ARE a handfull in wind. I spoke with a aero engineer and he indicated the problem is with the flat roof when used with a V-Nose, it causes all sorts of wierd technically sounding problems. (I just nodded my head and looked interested) The bow wave and side sucking effect is really pronounced...
