My experience with scissor steps was the further the steps extended, the more the downward slope of each step increased making them dangerous. No problem with the geometry or steps being equal angle. Learned when leveling rig to only use blocks on front axle, or dig holes for rear axle to keep stair treads level. BF has eliminated scissor steps on my newer 10.4 with a larger bumper and travel trailer type folding steps. Came stock with a 2 step and I replaced that with a 3 step which works great for two nearly 80 yr olds!
