IMO - if these are used on concrete slab and not dirt they will probably help with the stability of the trailer and not make the trailer swag or dip to that side when you step into the trailer
If it is used on dirt - I would have to say they will probably be worthless unless you use a flat piece of 2x6 (maybe 2 or 3 foot long) under it IMO.
you shouldnt have to relieve any stress on the steps unless you carrying a ton of weight when you get into the trailer.
