I own a 14 foot tandem Cargocraft V-nose trailer, I bought it three months ago and equipped it with, two torsion axles, rear ramp, two top vents ( one framed for a/c), insulated, two rows of e-track, rv latch on side door, and two flow thru vents. The ride is really smooth. I had my wife drive with me in the back on a patchy asphalt ranch private road.
