Hi guys. I have a 2001 GMC Yukon SLT with about 225000 miles on it and i have never towed anything. It runs perfect just like the day i bought it. My question is, I need to tow a 1973 Impala which weighs anywhere between 3500-4000 lbs without a trailor. the Uhaul trailor weighs about 2200 lbs which is a total of about 5700-6000 lbs total weight. I will be towing for about 350 miles and I wanted to know if my Yukon is capable of pulling this much weight. It is factory just like the day i bought it. It has a factory tow package with a weight limit of 5000 lbs on the hitch. Is this too risky to try to tow the weight? Should I tow in Tow/Haul mode during my trip or do not use the tow/haul mode? Again I am new to towing so any and all information will be very helpful. Also, I do not know how to drive with a trailer(parking it, backing up).
