Hi, OP here.
Thanks for advice so far. I thought Inwas right on the rv questions, and it seems you all are in agreement.
As for the trailer question: it's a 35- foot gooseneck pulled by a non-dually pickup. Hauling four calves plus equipment like fans, haters, brushes, and feed to a calf show in Ohio. The calves are not for sale. No one in the vehicle had a CDL, not required at home. Both truck and trailer are registered in same individual's name and he doesn't have a CDL. Hipo said that its length made it commercial in Iowa. Fined for operating without CDL, no commercial vehicle inspection stickers, failure to stop at weigh stations. Hipo asked if they were carrying alcohol. Sure, two sealed fifths of Black Velvet in one guy's suitcase in the truck box....which the hipo demanded and poured out on the side of the highway. No one was speeding, everyone cooperated including paying the fines. Hipo was not friendly. In all our travels with livestock (ND, SD, MT, WY, CO, MN, IA, NE, KS, IL, IN, KY) they've never been pulled over for anything, so this was a real shock.
