I've been on two RV forums for 8 years and have never heard of anyone getting an over length ticket.
I've seen on the highways tag axle 45' coaches pulling enclosed trailers that were Ginormous.
I think I'd just take my chances. And hey....if you get a ticket then you can come back on here and be a first.
