Definitely not a caravan. Almost everything you'll get from folks on this thread is what you read right here. We meet about a dozen rigs from the related thread and virtually all were due to the signs we had had on the rigs. But all of the posts, comments, questions etc were very helpful before we left.
There are guided caravans that consist of 20+ rigs. Pre planned and paid in advance. There are pros and cons no matter how you choose to travel.
Some experience is good for the unexpected situations that can occur. And then there are those like the guy in his 19th day in Dawson Creek - he drove like it was an interstate and bent his 5er hitch - oops. As I like to say feel free to drive the speed limit or faster - just bring enough money to buy a new rig. :B
