I am seriously looking at a 1986 454 GMC 1 ton dually to tow my 5th wheel. I just totalled my truck and have searched the local market and found nothing that has impressed me. I know it's 21 years old, but has only 86,000 original miles. Carb needs a little adjusting but belts/hoses are in great shape, it fires right up. Tires are new. Only one thru spot of rust on the drivers rocker panel and a few surface spots around the fender wells, one tear in the drivers seat, nothing that can't be fixed. And it will be a classic in four years. Any suggestions on what to look for that might give me problems. Hey I'm a girl and can use some manly advise on this.
