Our main tow vehicle is a 1992 Buick Roadmaster Wagon, 350 V8, with factory 5000# tow package. We added rear coil over shocks, tranny cooler and Class 3 frame hitch, brake box. Our second tow vehicle is our 2004 Impala w/the bigger V6. Class 1/2 hitch. The Imapla tows ok for short trips, as long as you don't use OD. The Buick doesn't know anything is behind it.
