Drivers license requirements

I think it's worth having for a few reasons, primarily being that your Rv seems to qualify for the requirement. But also, you can learn a lot in the education required for it. As far as if a LEO ever asks for it, I would be shocked if a LEO even knew it was required. Most states are so vague on the topic and even seasoned Rver's can't come to a rock solid conclusion that says you'll be cited if you don't have it that I doubt if a LEO would ever try and measure the length and even if they did would cite you. Lots of doom and gloom about being at fault if you don't have it in an accident. I seriously question if liability can be a default judgment if you possess a valid license but the class is different unless it could be proven that the lack of the certain class lead to the cause of the accident. You hear all this talk about lawyers waiting to get this info, well there are defense attorneys also and if he can obtain documentation that it's 1" shorter than it's a moot point. All that said, I would get it if I had a 40' DP. I mean, why not?
