in CA at least, and I believe Federally as well it is pretty cut and dry, any bumper pull trailer with a GVWR over 10K, or any 5th wheel(not gooseneck) over 12.5K GVWR Requires a Class A CDL with very few exceptions. As to what a LEO will cite you for is a totally different deal.In formative, easy to follow, but I already pretty much understand that and know certain states have different laws how it all comingles with federal and other states is confusing for me anyway especially when your no longer driving commercially, have a valid class A with farm endorsement minus the med card. So if I drive across state lines, or out of radius intrastate with farm endorsement 26k+ non commercially would I get the book thrown at me probably, I also understand if I don't renew my class A I'll probably never bother to or qualify medically to get it back. So all endorsements, experience, and training I received to get it would be for nothing for me anyway maybe just funny fodder for others. Anyways I've had it for 20 yrs last job I had with it was working for a county in WI plowing where for some reason state law didn't require dot physical for municipalities in intrastate use as said earlier from what I've studied and read up on I can't legally work intrastate or even get a valid chauffer lic in MI without getting fed med card, but can legally keep farm endorsement with out it. Apologies for drift.
Class A*: Any combination of vehicles which has a gross combination weight rating or gross combination weight of 11,794 kilograms or more (26,001 pounds or more) whichever is greater, inclusive of a towed unit(s) with a gross vehicle weight rating or gross vehicle weight of more than 4,536 kilograms (10,000 pounds) whichever is greater
