I’m satisfied other than the pin being in the wrong hole, once it’s latched I can’t put the safety pin in. But fast shipping. Ordered on a Monday, received by Wednesday around lunch

AWESOME!
I came to etrailer because
I needed a "low profile" 5th wheel hitch. I scrubbed the internet and the closest I came to was a 18" rise. I found just what I needed made by Demco. The price was a little suspect considering even here the price was at least $250 cheaper than anything else on the eTrailer page. I live in Iowa and see Demco grain trailers all over the place and figured farmers don't generally buy the cheapest so what the heck. Before I pressed the "Pay" button I looked at the Demco website, saw they were located in Iowa and gave them a call. I talked with a rep. who said the company bought the hitch line a few years ago from a Canadian company and that they were selling well. When I told them the price from etrailer he said "Buy, you won't find it cheaper at any of our distributors" So back to the "Pay" button. Then it got weird.
Later that day a young lady called me from etrailer to inform me that the item was "out of stock" and did I want to wait, choose something else or get my $ back. I told her that I couldn't beat their deal so I said I'll wait, she said "OK it should ship in two-three weeks". I told her don't ship anything until you can ship the hitch and the rails. Next morning, I got an email, "Your order has shipped" Wait what . . . ?
At that point I jump on the phone and called etrailer's 800 number. Another rep says "can I help you?" I said how do you bend time? she pulled up my order and says "Oh I see what happened, another person had ordered the same hitch and also told them not to ship an incomplete order also" This guy was waiting for something to be completed in June and they reordered the hitch and he would get his whole order also. Cool huh? I love that kind of flexibility in business. Lastly shipping. My product probably came in at 130+ pounds. Everyone else wanted more than $100.00 for shipping, mine was FREE. I would say I saved about $300.00 by buying at etrailer. With a great money back policy you really don't have anything to lose.

  • Installing Demco Base Rails On 2007 Chevrolet Silverado 2500HD Flat-Bed Truck
    We do not offer mounting brackets for flat bed trucks because there can be so many different dimensions. You will need to fabricate brackets or have them made for the fifth wheel installation. My contact at Demco said they use 3/8-inch steel for the brackets they have and they said they recommend using three brackets for each side.

  • Parts Needed to Install Demco Fifth Wheel Hitch FWH-24P in 1998 Toyota T100
    I could not find a reference to that hitch anywhere. If you could tell me the manufacturer, or possibly send in a photo I may be able to help you; I assume you are looking for the hardware to install and while I cannot guarantee you we have it if I knew the manufacturer and model I could take a look.

    I went out to our warehouse to take a few measurements on the brackets that are included with the Demco Custom Mounting Bracket Kit # DM8553004 that you referenced. The brackets measure 6 inches long and 6 inches tall, with a width of 2 inches. The distance between bolt holes, on center, is right at 1-1/2 inches. I have attached a diagram with these dimensions labeled that you can also take a look at. This particular bracket kit is is designed to work with the Demco SL Series Base Rails...

    If you have a 2022 F-450 with the Knapheide bed model PGND-96 and a recessed ball, I recommend the Base Rails for Demco Hijacker SL Series 5th Wheel Trailer Hitches # DM6012. Along with the rails, you also need the Custom Mounting Brackets # DM8553003 to complete the install.

    For your 2017 Ram 1500 you will want to use the Custom Mounting Brackets # DM8553010 along with the SL Base Rails # DM6012. The Brackets # DM8553004 you found will not mount into existing holes on your frame.

  • Fifth Wheel Hitch Recommendation for Ram Factory Fifth Wheel Rail Kit
    I wish there was an adapter available, but Demco does not have a way to adapt their SL series fifth wheel hitches to fit the factory rail kit of a Ram like what you have. It would be time for a new hitch all together. The B and W Companion part # BWRVK3600 is a direct fit for the factory rail kit of your truck and would not require an adapter. This hitch is considered by many to be the nicest fifth wheel hitch around so we recommend it very highly.

  • Fifth Wheel Hitch Recommendation for a Flat Bed Truck to Use Sidewinder
    The only way you will be able to use a Sidewinder on your flat bed truck would be to have a fifth wheel hitch installed on it. For a fifth wheel hitch you would want the Demco Hijacker SL Series Flat Deck 5th Wheel Trailer Hitch # DM6076SL-FLAT. This is a hitch specifically designed for the taller beds of flatbed trucks.

  • Mounting Dimensions for Demco Hijacker SL Series Flat Deck Hitch on SL Base rails
    I went out to our warehouse to take a look at the Demco SL Series Base Rails # DM6012 that you referenced. There is a set of 3 mounting holes at each end of the rails. The holes are spaced apart 4 inches on center, with a distance of 10 inches between the 2 sets, on center. From the center of the last mounting hole to the edge of the rail at each end there is a distance of 3-1/2 inches. I have attached an image to assist. The left to right measurement on the bolt holes will be dependent...

  • Fifth Wheel Hitch Recommendation for Flat Bed Truck
    For a flat bed fifth wheel hitch the Demco Hijacker SL part # DM6076SL-FLAT would be a great options since it is designed for flat bed configurations. For rails you will need the # DM6012.

The hitch will be able to be removed pretty easily when not in use.

  • Compatible Rails And Mounting Hardware For The Demco Hijacker SL Series Flat Deck 5th Wheel Hitch
    The Demco Hijacker SL Series Flat Deck 5th Wheel Trailer Hitch # DM6076SL-FLAT is only compatible with SL Series rails like # DM6012 so it would not fit the standard fifth wheel base rails you currently have on your flatbed truck. You could replace your current rails with the # DM6012 along with the mounting hardware # DM8553003 to provide compatible rails for the # DM6076SL-FLAT to fit your truck.

  • Gooseneck Adapter For Demco SL Series Base Rails
    The only gooseneck adapter currently available for SL rails is the Demco SL Series Gooseneck Trailer Hitch for 5th Wheel Rails # DM5992, which has a 30-1/2" measurement from center to center of the pins. I would double check the measurement on yours as it most likely has the same spacing. If not, you would have to swap out your current rails for the Base Rails for Demco SL Series 5th Wheel Trailer Hitches # DM6012.

  • Base Rails and Brackets Needed to Mount Demco FWH-24P SL 21 Hitch on 1969 Ford F-250
    For your older Demco FWH-24P SL 21 Hijacker the correct base rails are the SL Series # DM6012. These base rails are unique to the SL Series hitches like what you have and they will run vertical along the truck bed (as opposed to horizontally across like most do). I called my contact at Demco to find the correct mounting brackets you need to install the rails on your 1969 Ford F-250. He stated that you will need to use the Custom Mounting Brackets # DM8553003.

  • Recommended 5th Wheel Hitch for Flatbed GMC Truck
    For your GMC Topkick flatbed, I recommend the Reese Low-Profile 5th Wheel Trailer Hitch - Dual Jaw - 30,000 lbs # RP30054. This 5th wheel hitch is designed for flat bed applications and will require welding a plate as well as bolting the hitch into place. Another option is to use the Demco Hijacker SL part # DM6076SL-FLAT which is also designed for flat bed configurations. For rails you will need the # DM6012. The installation of these rails will have to be a custom install done by...

  • Available Reese & Demco Low-Profile 5th Wheel Hitches
    We do offer low-profile 5th wheel hitches, part # RP30054 from Reese and part # DM6076SL-FLAT from Demco, but neither of these is intended for industry-standard above-bed 5th wheel base rails. The Reese hitch installs on the frame through custom welding and fabrication; the Demco installs in their own special SL series rails # DM6012.
