I have a 1998 Acura 3.2TL Sedan. I want to tow my just-bought '84 MacGregor 25. The car manual says 1500lb total tow weight max. The Mac weighs 2100lb total, incl. trailer. I've seen the Mac towed by much less than my Acura. Am I safe to take it on the interstate? I don't have access to a truck/SUV. Thoughts? Thanks.
