I have an 08 Acadia FWD with the towing package, and am wondering if anyone has towed up to 4500lbs or exceeded that number. I have a track car that I would like to start towing to my local track. The drive is about 120 mi each way and is pretty flat ground, and occasionally I might go as far as 300 mi each way. It wouldn't be more than 3 - 6 times per year, so it makes it hard to justify a tow vehicle. My car weighs in at roughly 3400lbs plus a trailer. I am considering two options for trailers, one is an aluminum that weighs in at 895lbs which would keep me under the towing limit or a steel trailer at 1500 which would put me at 4900lbs. The aluminum costs 5200 where as the steel is 2000. I got some advice from a road racing forum that the steel trailer should be fine because of the short distances, but I would be curious if anyone on here has done anything like that.
