Bought a 20ft Krause Disk at an auction about 30 miles from home last weekend. Since my flatbed has fenders unloading some equipment can be a bear so I decided to just tow it home 30 miles with the YukonXL 1500 (only 1/2 ton). Big mistake.The disk has a large harrow on the back and probably close to 300lb up force on the hitch-so the back of the truck was sitting up to start out. It trailered real nice through the auction yard. Then we hit the highway... As soon as I passed 9mph the disk (duals on each side) would start oscillating so hard side to side that I could actually hear the truck tires start to squeal. The only way to get it to stop was to bring the whole rig to a complete stop. I ended up drive home 30 miles at 8mph or less. Simetimes it would hit a pothole and I would have to some to a complete stop to get her straight again. 4 hours later I was home, low on gas, tired, and cranky as heck. But at least me or no one else got hurt. I am sure that was NOT good for the Suburban driveline or frame and suspension-though she still drives fine. I would have been better off to trailer a small tractor up there and pull it home with that instead of the truck. Lesson learned here is before heading out get whatever you may be towing up to speed and see how it trailers.
