Years ago I had an expirience of wagging the dogs tail at about 45 MPH. these guys are right, load your trailer properly and make sure the toung has enough weight on it to allow the tow vehicle to control the mass. buddy of mine towed for years with a short wheelbase truck, he had heavy springs on it and heavy load rating on the tires. that was about as good a rig to handle as I have ever driven. Coil springs don't make a truck inferior to load handling. but, I think, the condition of the bushings may make a bigger difference. I tow my trailer with 3 different
OT trucks 1 with 4800 GVWR- empty trailer only. I have had my car trailer get squirelly on a gravel road just driving it with this truck. 2 has 5700 GVWR and will handle a light car or smaller truck fine 3 has 7600 GVWR with ton overloads and this truck can make you forget you are hauling a loaded car trailer, good gears, good tires, tight front end. What this, way to long, post comes down to is, The condition of your truck and how heavy it's built, means a lot more than how long it is. IMHO, dave
