IMHO, I think a 31" is pushing it, and there's no way I'd hang a 33". I've seen people put up to a 35", but it's also really painfully obvious how much the carrier and body are stressed. For a 32", I'd personally be looking for a bumper/carrier combo, or mount it on the rollbar somehow. If I needed to roll with it on a temporary basis (no wheeling) and limited opening/closing of the carrier, I'd be OK with that.
