I do have the linked step in adjustable and black and it comes very handy for times when I drop the camper and need solid step before my bumper.
It has its limit.
Coming from construction, I do have lot of friends who had accidents due to cheap ladders and I think due those accidents some of designs available 40 years ago are no longer available.
So long story short, if you need to go more than 2 feet up, get Little Giant in the size that fits your needs best.
You will thank me later.
