The problem with most undersized vehicles when it comes to towing is not the 'power' but rather the lack of adequate brakes.

Next time you see some jamoke towing too much going 75MPH down the highway and think it's OK just remember your wife and kids could be coming the other way....

On a related note, I'll bet 80% of all new mattress sales are to replace mattresses lost on the highway. Cops should pull over and thrash anyone with a Sealy strapped to the luggage rack of their Explorer.
