See a lot of threads regarding 3/4 ton suburbans, but none on the 1/2 ton lineup! Anyway, I have a 90 v1500 with the 700R4 and I'm considering hauling a 76 Plymouth duster on my way back from visiting Tulsa, ok. It's about 1k miles and lots of big hills. The car itself weighs about 3,200lbs and will probably put it on a u-haul trailer. how will I fair with 214,xxx miles?
