Yup - Agree with both. I'd say tongue weight would probably be your killer on the littler SUV since the trailer most likely has surge brakes. Just because it may have a tow package rated for XXX pounds on it doesn't mean the suspension is going to hold it up!

It's amazing what some people get away with though. I posted pics before of this guy I ran into earlier this summer that blew me away...

Really big boat...


Really NOT so big tow vehicle...


Talked to him and he admitted it was stupid/crazy but he was only going a few miles up the relatively flat road.
