Years of aggressively experimenting with towing combinations make us the experts.
These guys have much less of a clue than they think they do.
Just because you can hook something up and get it moving doesn't mean you've got a combination that makes sense or is safe.
My 98 K2500 turbo Diesel pulls an 8500 lb trailer. It's right at the rated limit and boy you know it.
I've also had an intrepid and pulled a loaded up utility trailer, over the cars rating. You knew you had too much weight behind that one too.
I especially liked their "proof" of Intrepid's and 300C's towing (since I had one). The trailer had the car bouncing and porpoising all over the place. Bad combination, very bad. Not to mention that movement will eventually fatigue the attachment points in the unibody and compromise both the car's integrity and the hitch attachments point (let's not even get into the fact the car isn't rated for the weight hitch required for the trailers being towed). Very, very bad combination.
Like I said, just because you can get it level and get it moving doesn't mean it's safe or even makes sense.
Let's not even get into the legalities of it all.
Try traveling to BC with one of those combo's and see what you get. Hint: it'll be a nasty surprise.....both when you have no brakes heading down (even you can even get it up) the Coquihalla pass or when the RCMP pull you over.
I'd avoid anything these London Ontario boys recommend. "Buck shee" is a word that comes to mind. "Flatlanders" for sure....
I've been to Europe lots, I've seen what they do. Same disclaimer; just because you can get it hooked up and rolling doesn't mean you're doing it right or safe....
