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. Jeff Hauser. 378683

  • 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. To see 5th wheel installation kits for your truck use the link to select your bed length to then see suitable base rail kits.

  • Dimensions for Demco Custom Mounting Brackets # DM8553004
  • 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.

  • Recommended Fifth Wheel Hitch for 2002 Ford F-250 Flat Bed
  • The Demco Hijacker SL Series Flat Deck 5th Wheel Trailer Hitch # DM6076SL-FLAT is designed for flat bed trucks like the one on your 2002 Ford F-250 so it will work well. You will need to install Base Rails for Demco Hijacker SL Series # DM6012, though brackets are not available for a flat bed so these would need to be custom installed by a professional at a local RV shop or other qualified individual. I've added links to video reviews of both parts for you to take a look at.

  • 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.

  • Can Fifth Wheel Hitch be Installed in Truck with CM Flat Bed
  • Fifth wheel rail kits need to attach directly to the frame of the truck. So what you are looking to do is technically possible, but would require some serious modification. 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. Flat beds are higher than standard truck beds so you need a shorter fifth wheel hitch. For rails you will need the # DM6012. The install of these rails will have...

  • Assuming the rails on your 2016 Chevy Silverado 2500HD's flatbed are industry-standard distances of 22” front to back and either 20-5/8” or 29” wide you can use any sliding fifth wheel hitch. In terms of a low-profile hitch that will fit industry-standard rails the Pro Series # PS30094 (15,000 lb capacity) or # PS30121 (20,000 lb capacity) each have a height setting that is 13 inches at the lowest; additionally, each of these hitches offer 10" of front to back travel.

  • Recommended Clearance Between Truck Bumper and Fifth Wheel/Gooseneck Trailer
  • It is generally recommended that you have at least 2 feet between the rear bumper of the truck and the fifth wheel trailer so that you have clearance around corners. I can't recommend you move the fifth wheel hitch behind the axle center as that will unload the front suspension slightly which will affect braking and turning in emergency situations. 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...
