Yesterday, when I referenced heavy weight on the latest built Redwoods I was mistaken. Their GVWR's don't exceed 16,500lbs. Also, their scaled dry weights don't exceed 14,500 lbs. Obviously, a Redwood trailer will never need to have larger than a one ton dually tow them.
I am looking at DRV's and have glanced at the Redwood brand. The nu mbers that I referenced were from DRV's. They're running right around 16,400 - 19,000 plus right out the door scaled dry weight.
DRV is the one that offers 8,000lb axles standard equipment. They also, offer a tri-axle set-up on the 19,476lb. dry weight unit.
