Do rv's with cargo trailers have to stop at Ag. stations?

I have read everyone saying that rv's alone do not have to stop at agricultural stations. I never do, nor at weigh stations. I have just purchased a cargo trailer, however, and I can't find an answer. The Florida ag site says rv's are exempt, but doesn't say anything about rv's towing cargo trailers. They say trailers that produce or transport, or could, ag products,need to stop. In Florida, pickups are supposedly required to stop if the bed is covered. That would suggest to me that I am required to stop, even though law enforcement may do nothing if I blow by. I am plannig a trip in a few weeks from Florida, up to Ohio, over to Massachusetts, then back to Florida. I guess when in doubt, pull in. Just wondering if anyone has ever gotten in trouble for not stopping at any agricultural station in an rv towing a cargo trailer. Also, my total weight, with trailer, will be about 11,500 lbs. Most weigh stations that I pass say over 10,000 lbs must stop. Any thoughts?
