What about the stacker requires a CDL? My impression is that they aren't necessarily any heavier than a long trailer with the same capacity.
3 axles on a stacker are likely 7k axles = 21000 gvwr trailer. A truck required to pull it has a 10k+ gvwr. 10k+ 21k= 31k. 31k > 26k = cdl. Rules are different when your trailer breaks 10001 pound gvwr. Even if they are 5200# axles, that’s 15600 minimum(and some of those are rated at 17k because tongue weight goes on the truck), modern 1 tons including srw are rated at 10500+ gvwr. My srw crew cab long bed is the lowest rated 3500 ram at 11700. That’s why lots of trailers are “rated” 9990. There are lots of different rules but this is the basic way to explain it. Even if you are not commercial, you still are required to have a cdl for most combos that large. I studied the rules very closely when picking my rig and had to decide between buying a rig with a combined gvwr of 26000 or less, or getting a cdl. Hence why I don’t have a dually.
it’s not the empty weight. The capacity determines the license requirements.
True, but there are plenty of trailers that don't need a CDL but could still haul two cars. I towed 3-car wedges without a CDL, but that was many moons ago before the new DOT stuff happened several years ago.
I haven't kept up with the new DOT laws other than the rule that you no longer need a CDL for air brakes (mind blown), but it used to be that single vehicle under 26k and trailer under 15k = no CDL required. (speaking GVWR of course, not GVW). Single vehicle over 26k and trailer under 15k was Class B, single over 26k and trailer over 15k was Class A.
The question I have is... Do you have a DOT number? Are you a commercial entity? If you are, scrutiny abounds. If you are just a grassroots race team, you still need to abide by the law, but you aren't a target.
Your post makes me wonder if you used to live in CA. They have laws that might cause questions like you asked.
Here is the skinny... the law is the law and you should follow it if you don't want to be afoul of the folks who enforce it. Having said that, if you have a DOT number on your truck you are subject to scrutiny from the DOT patrols (the vans you see at weigh stations here in PA). If you don't have a DOT number, you don't. They CAN stop anyone who looks unsafe, but their target is CDL stuff. When I used to drive motorcoaches, I was supposed to stop for weigh stations, but I didn't. They know that my GVWR is highly unlikely to be overweight. They're after tractor-trailers and the guy with an F450 towing 4 cars and a DOT number on the fender.
Basically, if you have a rig that looks like the first picture below and it has a DOT number on it, you're on their radar. If it doesn't have a DOT number, they will only pull you over if you look like the second picture.
