The problem is established. The fix could be one of three (actually four) things.
Buy a shorter set of steps...MORryde or other brand and replace these. Yes, it's not fair, but the retail value of the steps is about $350 or so. You could bite the bullet and replace them.
A circular saw with what used to be called a
"carborundum" blade would make short work of cutting off one step. Make the cut, use a mini-grinder to clean up the rough edges, paint. Then drill holes to match the originals to enable you to use the pins on the legs (and paint)...which you'll need if you take 4 to 6 inches off the legs. Buy a couple of blades, because you'll probably consume at least one or two.
Submit a warranty claim and wait. And wait. And wait. And then surrender your rig for weeks or months while they get around to it.
When I bought my rig, it came with
conventional slide away steps...just two. I wanted to upgraed to the MORryde step, because I boondock a lot, and conventional steps hang down in harm's way. The MORrydes' fold up out of harm's way when going over rough terrain (I've been 1/2 mile down an ATV trail with mine. When I asked what size to buy, they had a standard formula to determine how many steps. They measure from the gound to the threshold, and a MORryde chart said mine called for 3 steps. (Yours probably did, too.) But they ARE a bit long, and I often need to remove the legs entirely on level ground. On the flip side, when boondocking on lake shores, there is ALWAYS a slope from the road side to the curb side, and I need to lift the rig, so invariably I need to extend the legs. In those cases, two steps would not be enough, and the extension legs would not be long enough. So a lot depends on your habits.
If you're an RV park camper, replace or cut your steps. If you're into a mix of "resorts" and dispersed camping, consider one other alternative. While unlikely, if you look under your rig, you may see the frame attachment structure for conventional steps. You could replace your MORrydes with regular old RV steps, and you could buy an
adjustable "stool" step for when you need another step. I have one of these that's almost brand new from my previous rig. And I have a brand new set of aluminum conventional steps I took off my current rig and replace with the MORrydes.
Again, not fair, but you have options if you're willing to do a bit of work or throw a relatively small amount of money at it.
