New Steps Needed After Axle Flip - Recommendations?

If the frame is too wide for your camper then I would say to go to the GlowStep Revolution- 3 Step MFG Part Number: A8103

It is quite pricy but is probably the best RV step made and it comes in the size you need. I find it hard to believe however that the standard RV step you are looking for is not easier to find. That size door is almost standard as a rear door on all two door trailers and almost all of the smaller trailers.
