I use my 86 k5 with 350 to tow. My last long tow trip involved pulling my car trailer (1600 lbs) with 3800 lb car riding atop from VA to CA. I-80 was treacherous for my rig. Lots of cross winds, swaying, braking problems, especially down hill. I've owned the truck since new and have towed from Alaska to Florida and across the US several times. This was clearly the worst experience. Anything I can do to improve the towing characteristics of this short wheelbased k5? It is stock, has 192K on the odometer, 3.08 gearing, stock springs but a 350 engine not the 305. Can't afford to lay out for a new longer wb truck. Ideas please? Thanks!
