[fun w son]

i have a trailer that a friend gave me for my son's 14' hull. it was constructed out of several parts from other trailers, no papers at all. i am trying to get a plate for it. we went to state police troop C and they wouldn't even come outside to look at it... they said we needed a paper from DMV... DMV said we need a vin and receipt from state police.... can anyone tell me what i can do, or who i need to call??

thanks..
