Actually, depending on the vendor, they are a little of all three. If you check the post on Rally specials you will see that you can get some deals while at the Rally. Dexter axle for instance will sell brakes and seals right off their truck very cheap. At the same time Dexter's presentation will be part training and part question and answer so that you can learn and possibly fix or avoid problems. Over the years a number of vendors have also gone to look at issues with their products on rigs parked at the Rally. So the answer to your questions is that there will be all of the above and sometimes all of the above at the same time. You will learn a lot and have fun doing it and you don't have to spend any more money, if you don't get talked into it. If you look at some of the mods some of us have (show and tell thread) you'll see some of us aren't real good at avoiding spending more money.
