I have had them on my last 2 campers and really love them...They are 100% fully adjustable and you can also adjust each foot by itself for side to side adjustment... I have NOT had a problem yet using them..
As far as the dirt inside the camper..... I have a hand whisk broom as i am folding them Up I give them a fast sweep...
** So it sounds to me that we can add the new steps into the same category as :
Slide toppers, trip pod stabilizers, brands, trucks, and the list goes on..
It's all personal preference . . TO ME the stability they give are second to none !
