how to use this?

It works like a tow dolly, there are straps that go over the tires and attach to those bars. Three immediate problems come to mind, though. First is weight. You'll need to have a lot of weight over the front to make up for the extra weight on the tail. Second is height, but that might not be an issue if it's a pickup or van on the back. A car will likely drag the rear bumper under certain circumstances on there. Last is vehicle dynamics. As the truck and trailer sway back and forth, it'll set up a dynamic in the rear towed vehicle, which is commonly referred to as a wiggle wagon with good reason.
I'd also check into the legality of this wherever you plan on hauling, in certain states it may be considered doubles, or even improperly loaded.

 

That is an attachment for a second car for sure, have seen them in use before. The pivot point is accomplished by leaving the steering of the towed car unlocked, it pivots as the steering wheels turn back and forth. If you look closely at it you will see the strap and ratchet built in, this strap goes over the wheels of the car in tow and secures it to the deck. As for getting them up there, they use short ramps that are then taken out from under the car after it is in the cradle.

As 4x4 said, check with the areas you plan on running in, not all areas allow double trailers to be pulled by private individuals, and as he said there also will be the weight transfer and balance issues that will make driving interesting.

Personally, I never have liked this setup, I think it is dangerous and looks shady going down the road, you are just asking for extra scrutiny by law enforcement if you haul the second vehicle with that trailer.

 

I would say if you plan on towing 2 cars get a CDL with doubles & triples. Also some states like here in CT the car on the ground has to be registered. Tow companies here use dealer or repair plates when picking up cars on the hook, flat bed they do not. If cough you get a fine and have the car towed away that you then have to pay for.

How often you tow 2 cars? Might of been best to get a longer flat trailer that would hold 2 cars. Then you get into what can pull it and that goes for your trailer now with the added car in tow. That 2500? may not be rated for it and with a 2nd in tow on the ground I would say you will be pulled over and checked out.

Back in the day I had a 35 ft 2 car trailer used to move cars to/from auctions for my used car sales lot and off road race Jeeps to the tracks. We used a 76 Ford E350 van (460/C6 auto) to pull it and can tell you on the high way it was good but some of the off road tracks had steep drive ways we would need to freight train (chain other trucks to it) to get the rig to the pits.
Truck & trailer were kept clean and in nice shape to hold off police/DOT but they were not bad back then like today.

bryan2, with you pulling it with a 3500, what is the gross vehicle weight rating of the 3500? You have stated the trailer is rated at 12,000, so if the gvwr on your truck is over 14,000 then you will need a cdl a even to pull this empty, unless the cars are just for your own use, not resale or repair, or any other type of commercial purpose, and be prepared to prove it to the cops when they pull you over. The requirements for a class a are any combination of vehicles over 26,001 in gross weight rating with a trailer over 10,001 gross weight rating, doesn't matter if you actually weight that, it goes off strictly the weight ratings.

 

I have never seen one like it. Who made it anything on the paper work you got of make/model/year? I know the 1 car trailer I have now think is a U&W but paper work does not say that
When loading something on that trailer is there something you lay over that part to smooth it out or does it have to "fall" into that davit before getting on the flat part? If not could be a pain if you have to push or winch the car/truck on the trailer. I use a 2 speed hand winch on my 1 car trailer for dead cars/trucks and just getting over the lips from ramps to bed is a PITA.

That truck should pull good from what I hear. I almost bought a Dodge 2500 diesel years ago but when they told me I had a hit on my credit I walked away. Only thing you would need to check is the pulling weight limit for the hitch used and what the truck can pull. I am guessing class 3 frame receiver and 2-5/16 ball or is it a pintail hook?
My 2 car trailer E350 was 2-5/16 ball no sway control or weight dist. but my 1 car on my 02 Durango I use 2-5/16 ball & weight dist.

First and fore most for safety on the weight but with all the hot shots out there now, DOT on the hunt and a setup that could be commercial if you were to get pulled over why not have everything legal looking at a glance. That was the reason for a clean looking van & 35' trailer when racing.
Also a old time trucker said DOT was less likely to pull you over if nice looking, guess they thing you must keep up on everything else.

You got my goat. you now got me looking for that trailer you have just for information too. Did you have a year or make? I am still Googling to see if I find something.
