Steve,you are correct.Fred I told the pleasent officer that I raced for a hobby not profit,he said he didn't care if I got a trophy or blue ribbon for a pie contest,the State Of Pa wants their money and I will be bound by the gross vehicle weight regulations if I was carrying goats,pigs,gerbils(for Fred)There is no distinction for profit or non-profit,the only exemption would be for Receational plated vehicles.So if your hauling you Aunts upright piano and it puts you over your gvw your screwed.
