I have a Travoy, too... have you ever had any tipping problems with yours? Have you felt awkward loading your groceries directly into it while shopping & using it as a cart? Those are probably the two biggest issues I've had with ours, so I've been trying to get more information. Thanks. (not trying to derail the op's original question, though)
