I had no problem installing the port hole on my door.  I had no extra room on the flange, but it all worked out just fine and I've had no leaks or other problems other than very slightly compressing the Styrofoam when I tightened down the through bolts that hold the port hole and ring on place.  

Who ever wrote that declaration may not have actually installed one or got one with a flange that was 1 1/4".  When I return from Colombia, I will look up the one I purchased on Amazon and will post the link for that particular porthole.  Motor7, since you are relatively new to the board, you may not have noticed that sometimes people post statements in the absolute when they don't really know all the facts and variables.  

Why would would you want to go outside during a Zombie attack?  And if you succeeded in opening the door blocked by the handrail they'd spill into your Pod and you'd have to invite them to dinner.  It'd be awfully crowded in that case and hard to cook.

Take a look on Amazon, they may have the thickness in their product data.  And, if you order from them, you can return it if it doesn't fit and get a refund.

Anyway, those ABS/plastic portholes are all over ebay and not a single one lists the thickness. They are cheap enough that I am just going to order one and see if it will fit. 

Here is another problem, if you have a window or porthole, and you reach out to move the grab bar won't the Zombies be able to grab or bite you?

There you go.. just takes practice..

Motor7, Nope, that's not the one, but it is very similar.  I got it from Amazon.  The thing that you have to be careful about is that the porthole flange is deep enough to penetrate the thickness of the door.

I checked and the one I got doesn't seem to be there any more.  They do have the brand in your link info.  

To check the thickness of the door, you can remove the latch on the inside and measure through the hole from one side to the other.  I'm in Colombia right now so I don't have access to the cut out I had left over, but as I recall it was about 1 1/2"  

If you install the port hole assembly, be sure to measure how far you need to reach to release the handrail.  I didn't, because it never occurred to me that being trapped inside would be an issue, but by dumb luck, I put it where I can reach it. 

By the way the little world thingy at the top of where you write, next to the spell check turns your pasted link into an active one.  But, sometimes the window doesn't open all the way and you have to drag down to the bottom of the window to find the soft key to click. As for the link reducer, I don't have a clue.

Did you use this one?

I cannot open the door on my 2018 180 if the handrail is closed on top of it.  There was another thread a few months ago about this.  Everyone told me the same as they are telling you and even showing you in a video.

I tried to explain that there must be a different design on the older pods' hand rails but no one seemed to believe that and insist that I am just not pushing hard enough.

P.S.  I did not and am not going to file on the locking mechanism.  I'm a skinny old man but pretty tough and will go out a window if that bad guy locks me in.

I am left handed. I guess that is why it bothers me.  I guess it just bothers me in that I have been doing a lot of test drives trying to get my WDH set up correctly.

Good to know you can force the handle open if needed. 

We re-keyed the outside storage door and the outside shower door to use the same key as the entrance door. One key opens them all! I also "adjusted" all the latches so they latch firmly.

Don't worry about it. It is pretty easy to push the door open and pop the handle away. If you try it and can't do so, a little filing of the edge of the plastic to make a little ramp for the handle will fix that.

As for the storage door, you could reverse it, but the better option is to make sure you lock it before towing. I think it is set up for a right-handed person to be able to use the key easier. If you are left-handed, I guess you could switch them. Then you will have to make sure you turn the finger lock or you will have the same situation.
