RV and trailer lenght.

None of those sites that list length, doubles etc are ever right. The only way is to contact each state individually and even that changes so often you might not ever be right. Nv rv was 75ft, now reads 70ft, used to be needed endorsement for doubles now you dont or do you ? Might have changed today. No overall length limit here for trucks but they limit trailer lengths. Can go to 129,500 lbs with the right combo. How in the world could you ever know whats right in your own state let alone in other states.
