I would suggest you take your tape and measure the ground clearance you have available and discuss the measurement in relation to the product you are interested in with your friendly caravan parts retailer. I assure he will be able to help you.
Ground clearance for the step is a Problem on a lot of vans, we have even taken the single step off our van and instead use one of the free standing steps with the fold out legs that are available at most caravan and camping stores for about fifty bucks. Landy

Can give a problem when up against a concrete slab . i would stick with the single step and carry a heavy duty plastic step for the times when you need a bit more . I have bad knees and thats what we do . works well .
Why bother with them I have seen so many vans with the steps bent from runniing into things ,theres nice little step platforms like the ones Aldi sells .we just turn it upside down and put it on the door step when travelling, takes all of a few seconds to place it on the ground at your destination ...
We have a dual pull down electric step, one of the best things we ever got, no more wobbly step, much more secure. You really need to find one and check the dimensions when fully down to see if it will fit on your van, I think its likely it will.
The 2 step ones I have seen take up the same drop down space when folded in, so should be OK for you. But check out the width etc compared to what is already on your van.
I have a Jayco Sterling Outback and the one step was too high, so swapped over to a 2 step pull out. Had to strengthen the step well as it was beginning to weaken with just the one step!
