Not an Astro, but
I pull my 26S with a Ford Ranger, which seems to surprise many people. In fact,when I bought it, I drove to Staten Island and pulled the boat home to North Carolina with the Ranger, and had no problem up to 70 on the Interstate. It wanted to wag a little if I got over 70. Had some difficulty with traction on a very steep slippery boat ramp on Staten Island, but none on the highway, and none on the local ramps. I have a 3.0 litre V-6 with a 5-speed manual transmission. Don't know what your Astro has, but maybe this will give you something to compare to.Where do you sail? I'm about 50 miles east of Raleigh, and I generally go to the coastal sounds or north to Kerr Lake.
