That is the rear hitch step, correct??
I like this!! That stock side step is useless... I have been looking at how to extend it out so that it can be use...
How do you have this secured to the stock structure??

WACHUKO - Yes, it is. Source a 24"x8"x1/8" steel plate. Spot weld or bolt to attach to existing metal step. Bolted for now until I am sure that I really like how it looks. Then will spot weld later.

Any before and after pic? I don’t know what the “before” looked like.
I almost broke my skull numerous times at last year’s Houston RV show. I was a slow learner and kept slipping off too-narrow running boards on other brands of Class B. I really like the old Interstates’ running boards which are big and some would say ugly. Like the analog to 1970’s bell-bottom pants. But I don’t slip off of them.

INTERBLOG - well, if some think the old running boards were ugly & they work, I would rather have ugly & safe, than blingy & unsafe. My original steps have got to be the stupidest design from AS. My wife also has had many near misses to a serious fall. And she's an adult. I have g-kids to worry about. I said that's it, I have to fix this. If I can make one that is safe and still decent looking and actually structurally better than the original (they had 1/3 of its topside parts held together by doublesided tape), then it ain't that hard to do.
Pics below (3old-3new) for comparison
OLD
My NEW Prototype - almost ready to weld after
next weekend's trip, assuming no failures. Wife, daughter, & grandson already tested & approved.

Expound:
What I said (blogged) back in early 2017, screengrabbed below. This is a nasty hazard because it is a set-up for a tailbone injury, which can be seriously disabling. I don't know why the corporate risk management people did not flag this type of design as unacceptable.

T1N Interstate for comparison: look at the way they flared that running board in front of the slider. In four years, I've never once slipped on that thing. It's so wide there that I can also use it as a seat. That's how to do it.

Agree that the stock steps are useless - which is why we never use them. But as we age I am sure that we will want/need some step.
Does your modified step rest on the existing step or does it sit outside of the existing step? Looking underneath mine, the existing step is bolted to two 'C' channels. Couldn't you bolt your modified step to these same C channels? What is the width (perpendicular to van) of the tread surface of your new step versus the original.

Alex - I see some improvement in your new step but I’m afraid it’s still not quite enough to allow for “face-out” exiting due to potential heel slipping.

TITUS - It rests on existing step. 24"x8"x1/8" steel plate bolted on top (will post pic in a minute as I get it outside). 75% of plate is supported by original step. The other 25% is cantilevered. 9 stainless steel bolts temporarily support the steel plate onto existing steel step. The running board is bolted onto the new steel plate and into the original steel step. Bolting it to the C-channels creates issues I did not need to deal with. The other reason was so the new step would be at the same street-to-top-of-step height as the Project2000 power step on sliding door side. Step itself is 4" wide x 36" length. It sits approx 1.75"-2.0" past edge of original step.
AIR99 - Yes, I am perfectly aware of that. However, one still has to balance the aesthetic with the functional with the maximum protrusion of step (i.e. it is past the outer bounds of front/rear track & well within the outer edges of side mirrors. I can not push it out to a depth that allows my size 8.5W feet to exit "face out" with entire length of foot inside the step. But I can exit face-out approx. 2" much safer than any un-modified AI NCV3 (not sure about the new 2019). Pushing it out beyond that point, the design would look outrageously ugly. I have already gotten much criticism in this forum for putting forth ugly designs for brain-storming, which is fine. That's the time to weed out ugly. But I know ugly when I see one. I can only go that far in the drawing stages, but I am not about to go that far once it is installed. In fact, a prior design that I prototyped just extended the original fiberglass mold. It was so ugly and proportionally horrible, it never got bolted on. (pic below)
As my unit stands, it is already protruding approx. 2" more than original. I like the balance between aesthetics, dimensions, proportion, and increased safety. My objective as noted in the title is to prototype a "safer" step, not the "safest" step. Side-step exit is 100% safer for my 8.5W with 4" step & 4" wide foot. The design allows for another 1.5" adjustment fore/aft and depth. But I doubt I will change it.

This is what I was thinking of doing!! A flat plate that I would install on top of existing step and build borders that would match that of the original step... paint it all silver to match, install grip tape and done!
It was that or looking at how I could integrate electrical step, like the one in the sliding door...
Looks like you cut that steel plate to do something similar?? Then changed direction and tested the longer step???
Just wondering if that is the case and what made you not to go that route.

WACHUKO - I initially did measurements to try to integrate the Project2000. Problem was that takes a lot more room undercarriage. It would've necessitated complete removal of the existing structure and the surrounding body skirting from the mudflaps to the sliding door. Even if I were to commit to that, my E&P levelers were also in the way. Would've been nice
Yes, I cut the plate to originally follow the 45° miter on original step. The idea was to just bump out the exact profile (f-glass & all) about 2"-3". Bolt it down and fabricate a metal filler in between to level the gap left by bumping it out. Then grip tape over & done. But as you can see from the last pic I posted for AIR99, it looks very odd proportionally. Coz the step is now sticking out 2" further, but it's the same length. By using the 36" step, I increase the length by 10"-11" while depth only increased by 2". This gives a visually slimmer profile and is not as abrupt as a 26" contraption sticking out further.
PS. I really like that hitch step as that was my original use for it. I just happened to stumble into possibly using when I removed it from hitch and laid it down near the side door. It is very well constructed and beefy, not to mention it has clean lines with the alu finish

I missed that update and the photo. Not sure if it is the angle of the photo or what, but that actually looks okay to me. It should be a fairly easy test for me to try out and decide on what route to take.
Thank you again for sharing your thought process and the photos!!
And yes! Can't jeopardize location for the install of the leveling jacks

It took me a while to teach my DW to back out, rather than exit face out. It comes natural to me to back out.
The original step is not ideal, but I'll stick with it.

DELORES - Thank you. I settled on it because it is a very simple look. In fact, it is a much simpler look than extending the original step with the mitered corners, as you can see I tried to do both. It is not hard to do, just need lots of patience in removing the enormous amount of double side tape from these old parts (see the 2 strips still on grey f-glass top trim). This is 3M automotive exterior mounting tape and do their job so well, it takes a lot of effort to break them free. I spent an entire day of removal/cleanup but only minutes cutting the sheet metal and drilling holes.

JOHN - Good to advice. Personally, backing out is my preferred egress process. I too have trained everyone to do so. I just remind my fam this - you usually go in to a parking spot, then you usually back out from the parking spot (it is harder to rotate the car to face-out of parking spot to get out). Seems to work, even with new step they have now established the habit. My F150 4x4 has retracting running boards and I never exit face-out, even though it has deeper steps.

WACHUKO - 2 pics different angle of setting up original step mold with 45° miter and bump it out 2". Also, undercarriage pic showing leveler proximity to step. But for you, you ought be able to install the Project2000.

Thank you for the additional photos!
I do not plan to install the Project2000. I do want to explore trying what you did by pulling out the stock step those 2" to see how it works and looks in the flesh.
Thanks again!!
