Feasibility of retrofit dovetail on 20' flatbed gooseneck trailer

I have a 18' car hauler trailer that I took the dove tail out to make a flat bed for my quads. On mine the frame rails are 3x5x1/4 angle that was "V" notched 18" from the rear to create the dove tail. On the off chance that I have a car to haul, I made up some 8' ramps.

The whole thing was easier than I thought it would be.

Best of luck

Were you planning on adding a dovetail to the end or notching and welding the back 4' or so into a dovetail? Adding to the end will mean looking at the frame rails going to the back of the trailer to make sure they are strong enough to take the bending load that far away from the axle. Cutting, notching, reweld may be easy or hard depending on the configuration of the frame rails. This would certainly call for adding suitable fishplate reinforcement as well as high quality welding. I'd also make sure that the frame is not some sort of high strength heat treated steel. (somewhat unlikely since most trailer mfg use common hot rolled steel shapes)

Axle placement is a functi> Greetings,

Thanks to all.

Roy: Your comments were especially thought provoking. Maybe I'll take some photos, post 'em on my web page, publish the links, and ask for additional comments from everybody.

What height is your deck?? I hope under three feet. A angle iron truss affair under the ramp will allow you to keep things light. Pics would certainly help. Randy

Randy,

Our digital camera went kaput. I only learned this yesterday. But I'll take some measurements and post 'em later.

I don't know the height of the deck but it's pretty tall. It's a 20' x
