I made this for our Arctic Fox 1140. The upperstep comes off with just two wingnuts to allow access to the basement drawer. material and powder coating $200.00
As for the welding, powder coating covers a lot of sins.
What you can't see in the picture is the larger bottom step is bolted across the back using the same bolts as the bumper and underneath are three supports that butt up against the bumper. The bottom platform is basically a permanent installation.
Only the top step is held on by the 3/8" bolts and wing nuts and they just keep it from rocking when you step on it.
