The 5spd is rated at 3,500lbs tow capacity, the Automatic is rated at 5,000lbs tow capacity. So it depends on what you're getting.
I have a '97 Pathy with the VG30 and an Auto, and I pull a 3,000lb trailer with a 2,000lb boat on it all over the place, and it has no problem, and never has. I've been doing this for about 8 years, it's got 160K on the original drivetrain and not even a hickup. I maintain it well, and don't ever tow with the A/C on or in Overdrive.
Towing another truck on a trailer may be pushing it, but I'm sure it would do it no problem.
