Hello neighbors, it's Brad here at etrailer, and today we're taking a look at the Demco Coiled Air Hose Line Jumper for your 2019 to present Spartan Chassis. Now, many newer RVs, they've caught on to the trend that people are flat towing their vehicles, and when you have air brakes, you do need to run this jumper cable. But the great part is, is you're able to get away with a second vehicle kit on your newer Spartans because the tank's already installed and you have a fitting here that says "tow brake." Now, the second vehicle kit does not come with this coil bind, so picking this up allows you to plug in directly to the tow brake fitting here, and then to the fitting on the vehicle, allowing the air to transfer to the main unit, bringing your brakes to a slow or stop. The line is not any different than your normal coil that you'd get with a full Air Force One kit, but this one has a larger diameter that works directly with the factory fitting on your 2019 to present Spartan. Your fittings are already threaded on so you don't have to worry about anything, you just simply hook up to your push connect fitting nice and easy here, locks in place. Do the same on your vehicle, and then you can transfer that air pressure over.
Now the coiled cable allows this to stretch, so distance-wise it's gonna work with really any flat tow setup to be able to hook up to your RV and vehicle without this being too stretched. So really any setup that you have, this is gonna work great on your Spartan Chassis..
The service provided by etrailer service representative Daniel has been extraordinary. We didn’t realize that our air jumper had disconnected mid-trip, and we had ordered 2 different replacements while driving (not knowing which part was the correct one) and Daniel noticed the multiple orders and called us immediately. Thru conversation, he corrected the order and refunded our $$$, and placed the order for the correct air jumper AND had it overnighted to us for next day delivery in tiny town (Cascade) in Montana!!! Unbelievable service and attention to detail. We can now tow our vehicle safely and will ALWAYS look to etrailer first should we ever need any assistance.
Exactly what I needed for my 2023 Entegra Reatta (Spartan chassis). Previous jumper came loose from our toad and dragged on the road, destroying the connector. eTrailer shipped to the RV park and got us back on the road.

I'm happy to hear we could help get the adventures rolling again for you and your family Mark. That's quite the RV you have! Do you care to share a photo of your set up?
This product worked great and I am still using it today, 1 year after purchasing it. The only reason I did not give it an excellent rating is that the coupler attachments are somewhat finicky and you have to make sure that they are attached well or they can come unattached during travel.
Exactly yet product that I needed and delivered in record time - Thank You!
Lori does a great job and is very responsive to customers. The problem is delays in shipping and then delays in transit. I understand the present day transportation nightmare, I'm in the RV battery business myself. If I would have gone to [online] I likely would have had this in 2 days. I've been a customer of etrailer for years, but the delays will be effecting my future orders out of necessity in getting parts on time.
Great product. I bought it as a back up for my AirforceOne Braking System.
New motorhome with different air hoses for the tow-had to come home without tow brakes. Quick shipping; what a relief!
The jumper is exactly like the original equipment. etrailer is my first choice when it comes to towing related products. Johanna was very helpful with my order. I used 4 day shipping and everything arrived as expected.
Excellent product. Works great on my Newmar Aire and Etrailer had the best price.
I ordered air hose on line, got a great price and it was shipped very fast. No complaints.
Overpriced, $100 with tax and shipping for a $50 at most part!
The product is good, but delivery very slow. 7 days from Utah to Southern Calif.
This was my first ti.e ordering from etrailor. I was in a bind and needed my part overnight. They accommodated my request and were fantastic to work with. I will definitely be a customer!!
Webpage was informative and easy to follow and select the right part
Customer Service was involved and received great information on progress of the shipment. Finally confirmation that it arrived.
Service and Delivery exceeded our previous order. Our Service department Places etrailer at the very top of knowledge and service.
Simply: THANK YOU
I only ordered it because you showed it would deliver in the third day. Missed that by a day after I had to leave. Your people said they would at least credit me for the extra freight. Haven’t seen anything. I had to go somewhere else to get it.
Perfect! Matches up perfectly with my Entegra Aspire - "fits like a glove"!
Great prices and lightning fast service!
Works great no issues after 1-year of use, would buy again if I need another one.
