¡Hola Oppito! Here's a VW towing a camper with a top-mounted hitch. What are those roof rails made of, unobtanium??

On to the question: why are FWD vehicles plagued with poor towing ratings? Is it a factor of the FWD drivetrain itself, or is the unibody more to blame?

That trailer probably doesn't weigh all that much...but still that is quite the interesting setup.

Fwd cars usually have much lower tow ratings because when adding the weight of a trailer to the rear of the car it will lift the front end so now the steering and drive wheels won't have as much traction. Also, because it is a fwd car the rear suspension isn't as robust because it doesn't have to contend with controlling the forces of a rear axle or diff transmitting the power to the wheels.

In a rwd vehicle, yes the front wheels steer the car like a fwd car, but the drive wheels would now have even more traction with a trailer than without. Also the same reason why a fwd car doesn't have a beefy rear suspension is the reason why a rwd car has a beefier rear suspension.

Thank you, that makes sense. I just couldn't put it all together in my head.

As well as what TJDMAX said below, also bear in mind that the US towing limits are completely different to those around the world. They appear to be a subtle form of protectionism aimed at driving people towards trucks. Here in Europe it's completely normal to see people towing with a FWD vehicle.

Not that I'm suggesting you get a caravan, but here are some caravanists' recommendations: http://www.campingandcaravanningclub.co.uk/towcarawards20…

It gives you an idea. It's also not uncommon to see small FWD SUVs used. For heavier duties where you guys would use a truck, we tend to use bigger SUVs, so not a great deal of difference.
