r u wanting the tube to be square or round. i just started messing with steel pipe like 2 weeks ago, one cool thing about it is as you draw it out the walls get thicker since the downward force causes it bunch up or upset set. so maybe start with way larger pipe, draw it out, i like squareing it up and drawing it out as opposed to fillling with sand or using a botttom swage, then twist while its squared up, andif you want it round, round it back out with a wood stump and wood mallet. that may do the trick but im sure there is a much more experienced smith who would have a better way

Short answer is yes you can twist tube, go too far and it will collapse and /or distort,

You don't give sizes or a rough sketch re attaching this to the vehicle, but have you considered using flat bar twisted with flat areas for the rungs to be secured to ?

Left hand twist for one side, right hand twist for the other, twists will give rigidity to the flat bar

We actually just tried twisting hollow square tubing. Just go slow. Slow and a couple heats and it turned out pretty nice!
