Welcome to the new RacePA!
I suppose a second lesson learned is that just because a owner's manual states a given tow capacity, it doesn't make it so in the real world. I personally believe it comes down to whether the marketing or legal department had final say. I have owned vehicles that have been over-rated and I currently own a tow vehicle that is seriously under-rated.
I just brought home my new tow vehicle. Its not your super heavy duty tow vehicle but it will be plenty for what i need it for. Its a new Jeep Grand Cherokee with a 5.7L V-8. (never had a V-8 before. lol). It has the hightest in class tow rating of 7400lb. I'm pretty excited to finally be able to tow my car. Now for the trailer. I've been looking at Aluminum ones but, they sure are alot more expensive then steel ones. Is it worth it?
