Getting away/under from the 10,000lb trailer is a huge benefit, as is getting under 26,000 combined gross weight ( trailer and truck loaded). Also keep in mind simpley hauling your personal items to a swap meet, whether you actually sell anything or not, is defined as commercial use, ie you were planning on reciving finacial gain. The usual solution to many of these laws is to simpley lie. Which I personally do not condone.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
