I know that everyone's experience and abilities vary. While I have witnessed many 5ers and TT being towed at 65-75 mph with skill, I have seen way more that handled their towable in very unsafe manners at those high speeds. Considering that there are so many possible hazardous scenarios that could develop while towing at any speed, the likelihood and severity of those hazards increase greatly the faster one drives. This not only puts the individuals in the TV at risk but others on the road as well. I for the life of me cannot figure out why people pulling trailers have to be in such a darn hurry. It's like they have to prove something. My theory is...well I'll just keep that to my self so I don't get booted from this forum. I say slow down, be safe, and enjoy the trip to the destination.
