Rear loading ramp for sled trailer

Baught a used trailer and on the way home the ramp slid out from the trailer.  It was pinned....now have to wait for new one....gonna be awhile.  I want to get the sleds out this weekend.  Anyone have a temporary solution or a spare ramp????  Located in neenah wi.  Used to a tilt trailer so this is a new adventure.

It's kind of awkward with the track in the middle RC as the track is a bit wider than 10 inches.  

If you did try it, you would need (3) 2x10's - it would work if there was not a snowbank handy.  

Maybe a silly suggestion but why not some 2x10s. I use them on my ATV trailer.

Call the manufacturer, they will make you a new one for around $300, I’ve lost a few in my day LOL  

Also, as a short-term solution, simply back into a snowbank and drive your sled right off.
