I often wonder about this. The manual for my boat says that you must not trailer the boat with the engine on though. The boat was sold to me from new and handed over to me with the boat on a trailer and with the engine on.
My trailer has a transom support and having seen the massive forces on the transom while under-way, I can't see any reason why it can't take the loads (like sudden jarring hitting a pot hole) while being trailered. I suspect the problem is that the boat gets most of its rigidity from being inflated. If the towing car threw up objects from the back wheels that punctured the tubes, there is a possibility that the engine would fall forwards (or backwards), then back out underneath the trailer. It wouldn't be a risk on a rib and less likely on a hard deck sib. But a possibility on any sib. If the manufactures feel the need to cover their arses then it makes sense to reduce the risk if/when we ignore the manual.
