When towing your vehicle with a tow bar, all 4 wheels are in contact with the ground. Certain vehicles - namely, those with front-wheel-drive automatic transmissions - require either a transmission lube pump system or a driveshaft disconnect when being flat towed. Using a tow dolly eliminates the need for those by lifting your vehicle's front wheels off the road. In addition, using a dolly eliminates the need for base plates that clutter the front of your towed car, difficult-to-install wiring, and a potentially expensive supplemental braking system. Also, if you want to tow multiple vehicles, this dolly is a great alternative to traditional flat towing because you don't have to purchase and install brackets and wiring for all of your cars.

Space Saving Kar Kaddy SS

Kar Kaddy SS Folded

The folding design of the Kar Kaddy SS allows you to save space in your garage and at your campsite. The tilting ramps and swing-away tongue each stow compactly against the dolly for an overall folded length of just 67". This maximizes space around the tow dolly when it's stored and reduces tripping hazards.

Hydraulic Disc Brake System

Kar Kaddy SS Disc Brakes

The integrated hydraulic braking system features Demco's eZ-Latch surge coupler and disc brakes for safe stopping of your towed vehicle. When the eZ-Latch coupler latch is in the closed position, drop the coupler over the hitch ball and the latch will snap into place. No need to pull the latch up to open the ball socket. The drop that's built into the coupler helps you match your tow vehicle height, and the included breakaway lever activates the tow dolly's brakes should it disconnect from your RV. All hydraulic lines and fittings come pre-installed with the hoses run through the frame.

Kar Kaddy SS Disc Brakes

Disc brakes provide more consistent stopping power and a shorter stopping distance than drum brakes for safer transport of your vehicle. When you apply the brakes in your motorhome, deceleration will occur and momentum will push the dolly toward the rear of your RV. This applies force to the surge coupler's master cylinder, which sends hydraulic fluid through the lines to engage the brakes. This design ensures that the dolly brakes proportionately to your motorhome, which helps to eliminate wear and tear on your RV's brakes. And, because the brakes don't require an electrical signal, an electric brake controller is not needed.

Wheeled Tongue Jack

Kar Kaddy SS Jack

The wheeled jack lets you easily move the dolly toward your hitch for coupling and then conveniently swings up and locks into place alongside the trailer tongue for travel. Drop the jack back down and roll the dolly out of the way when you're done towing.

Setup and Use

Kar Kaddy SS Assembly

The main components of the Kar Kaddy SS come pre-assembled for fast setup. Use the included instructions and hardware to attach the main frame to the tongue assembly, then install the ramps, fenders, mud flaps, and wheels. Finally, connect the pre-routed wiring.

Prior to towing, bleed the hydraulic system to remove any air from the brake fluid reservoir. Brake fluid is not included.

Kar Kaddy SS Tire Nets

The textured ramps allow for safe loading of your vehicle onto the integrated wheel platforms. Once your towed car is in place, drape 1 tie-down strap over each front tire. Secure the straps to the platforms, and then use the tie-down winches to easily tighten the straps around the wheels. Attach the included safety chains to your vehicle's frame and you're ready to set out.

Included tie-down straps fit most standard automotive tires. Straps for large (DM03528-93) or small (DM03528-81) tires are sold separately.

Built for Highway Use

Hit the highway in the quality, well-engineered Kar Kaddy SS. The steerable axle allows the tow dolly to track directly behind your RV, preventing sliding and binding of the tires. The dolly's radial tires create less rolling resistance and heat buildup than bias ply tires, resulting in longer tread life and improved steering at higher speeds. This makes radial tires ideal for highway use.

Kar Kaddy SS Lighting Package

The full LED lighting package is DOT compliant for safe towing. Brake, tail, and turn signal lights, front fender marker lights, and license plate marker lights are included to increase visibility on the road.

The galvanized finish resists rust and chipping. And mud flaps and rustproof polyethylene fenders protect your vehicle from flying road debris.

Tow your vehicle without installing a tow bar or base plates. This galvanized tow dolly features hydraulic disc brakes for safe, controlled stopping and folding ramps for compact storage. Fits towed vehicle tread width between 42" and 76".


Well constructed , it arrives in a large box so be prepared . once un packaged you need to put it together . Not difficult if you are the type to work on things like this . Tip they deliver curb side so you need to un pack and turn the unit sideways on the pallet then put the tires on while jacked up on the pallets this allows you to roll it to where you need it to finish the assembly in my case the garage 30 ft away .


Currently assembling dolly. Will performance review when done and used. The delivery was timely and driver very helpful as a team mate to get dolly in position in my work shop. My concern at this time is twofold:
- the fact that the unit has been sitting in storage for a long was somewhat understandable but the fact that the tires have a build date of about 2 and 1/2 years ago is very concerning. That computes that the tires are over 1/3 of their typical lifetime and this is for a brand new dolly. Hopefully e-trailer will explain
- packaging was horrid. Outer cardboard torn and crushed and wooden container broken with contents clearly visible. I did sign for acceptance of dolly stated condition to be determined. Driver checked that the packaging was NOT intact. A cursory inspection has not revealed any visible damage but this will evaluated upon assembly. Have not looked at plastic parts yet.
I have photos of the shipping container's remains if needed.


Package was heavy and had to improvise handling since I was all alone to assemble, but was able. As I recall, I had a little difficulty getting the hydraulic brake connection together, but was able there also. Materials all good quality. Dolly is HEAVY and difficult to move on anything but firm pavement. Foldable tongue is of limited value, unless you are really tight for space. Don't forget to remove the locking pin for the axle when you tow your vehicle, since you want the wheels to track properly behind your vehicle, and also to use it when you tow empty.


The brake bleeders are junk, one was cracked upon inspection, so I replaced them all. Other than that issue, it is an excellant product


The car Kaddy is awesome. Very easy to load- only 10 minutes the first time. About the same time as a flat tow. Somewhat easy to put together between the video and the instructions. The only issue was the brake coupler is not that easy to get together.


I tried to get this trailer from other suppliers to a horrible fail. etrailers was determined to get it delivered. I order it one year ago and finally was able to use it. I traveled from Boise to Vegas and it was easy to connect and tow my vehicle. The RV park I am at makes you store dollies in other locations unless you have one like this that folds. Highly recommended and glad for all the support from etrailers.


I think the instructions were really ba d.


Another GREAT experience with eTrailer!!!! They either quickly deliver a high quality product for a reasonable price, or they correct any error whether theirs or their provider’s without hesitation. In particular, Tanith and William E., as well as another young lady helped me navigate missing documents and a label damaged by a shipping company as quickly as I could hope for. Thanks again folks!


Perfect match with the wheels and tires that came with the dolly. Would never travel without a spare.


This is one of the worst companies I have dealt with. I ordered a Demco Kar Kaddy SS and it was delivered June 16. The package was damaged and the ramps and structural support bars were laying on top of the outside of the box. There was no hardware at all enclosed with the unit. I called and told them we were missing all the hardware and they promised they would ship immediately and we'd have it the next day so we could put it together and leave on our planned trip. Box showed up two or three days later and they sent us another set of fenders and no hardware. Had to postpone our trip. Called again and told them we were still missing hardware. Again, we were assured they'd send out that day for overnight delivery. Three days later we get the hardware. Go to assemble the unit and there is brake fluid all over the floor. The brake line connection to the reservoir must have gotten broken off during shipping so another no-go issue. Called them and told them to come get it and refund our money. What a screwed up company.


Have put 10k miles on it. Has performed well. Ordered replacement winch from Demco and it was covered under warranty.


We have used it three times now with good results. I like the steering axle. It really helps on tight turns. The assembly went well. I did it alone but a helper would be nice.


Pretty easy to use except for the ramps that suck. Almost impossible to use and align.
Delivery took forever and when it did arrive the box was destroyed and had to straighten a number of parts and wait a couple more weeks until they got me the hardware that had fallen out of the box.


The Kaddy preformed as advertised. The construction material and the wiring was of good quality. The instructions for the assembly were written professionally and provided photos and sketches where needed.


The only reason I am giving this 3 stars.
Being life has come up over the past year, we haven't gotten a chance to use it yet, except for a test drive around the neighborhood
Assembly was not very difficult, if that helps, and construction seems very good


Well made sturdy product. Need two people to put it together with two jacks or a jack and blocking.


Awesome tow dolly. Works just as expected.


Dolly worked perfect towing a 2019 Colorado From Upstate New York to Tampa Florida.

  • What To Do If Using the Demco Kar Kaddy SS On a Vehicle With Steering Wheel That Does Not Lock
    Correct, the Demco Kar Kaddy SS Tow Dolly part # DM9713045 does indeed call for the toad vehicle's steering wheel to be locked while in tow. If the toad vehicle's steering wheel does not lock then you will need to find a way to tie this off in a fixed potion, some use the seat belt. That said, I don't have any devices for this but there are some available. If you like you can reference the owner's manual which I have attached for you that further explains the steering wheel lock requirements.
