I've heard that the reason for max tow ratings is the ratings of the brakes on the tow vehicle. If I use a trailer with brakes on both axles can I exceed the tow rig's max tow capacity? My (potential) tow rig is 4295 curb weight, 5570 GVWR. Tow capacity of 5000. I obviously want to tow my K5 (+ trailer), probably 7000. With 245 HP / 280 ft/lb I would think that physically it should be able to pull it. Any thoughts?
