Mor/Ryde or =

The one that I had installed looks the same as the picture that you posted. Just doesn't have the 3 sticker. The one I had installed on the 29RK was the exact same pin box.

On our trip to Topeka and back the trailer just about beat us to death with all the bouncing and back and forth. Especially on the Interstate Highway system where they have the expansion joints. Had I been thinking I would have gone over to the Mor/ryde plant in Goshen and had it changed while we were there. The Roto-flex appears to work fine for some folks, but for my set up it was no better than a standard pin box. For my set up the Mor/ryde takes out the majority of the bouncing and back and forth movement when on a rough road. I had basically the same issues with the 29RK and the Mor/ryde solved those as well.

I called Tweety's and gave them my info and they said this is the one I needed. I don't think I want anything any stiffer. Might just as well keep the Lippert if you want stiff.
Let it work for you.

Update Again.
Tweety just called me.  Said i ordered the 18k pin box. heavy duty. And it would be tough for them to get. RPB72-1621SHD  Hats off to them to question it and notifiy me.   My order also states (under 11,500 lbs)

So the order is on hold until i figure this out, Because my camper is in storage and unable to measure, For at least a couple weeks.

If you look at Tweetys listing for the lipperd 1621.  It states RPB72-1621/HD* (Doesn't have the "S")  Under 11,500lbs.  http://www.morryde.com/uploads/products/files/53/Pin%20Box%20Identification%20Guide.pdf

If you go here, http://tweetys.com/morryde-fifth-wheel-pin-box.aspx it shows two listing for the Lippert 1621..  The bottom one will give you the S, And the top one won't.   Both for under 11,500lbs..   

SO do i have a S ? I think i just need a HD.. Not SHD    the SHD will ultimate result in a 18,000 plus pin box, Even though the order stated under 11,000.

Confused.  They said folks send them back all the time because they aren't right.  They said to measure it. Tweetys site only shows the HD, dimensions.  Also the moryde site don't show me dimensions for the SHD either.  Just the listing that shows the SHD is in the 18k+ weight range. http://www.morryde.com/downloads/technical/Pin%20Box%20Identification%20Guide.pdf

Thoughts..  ?  Just order the RPB72-1621HD Under 11,500k ?

Now the pictures.
Tweety is the only one that mentions the "S"hd.  Shows two options for the 1621. Moryde site don't show the "S"hd option at all. 


Tweety another reference to the "S"hd.. Again, No mention of that option on moryde's site


Morydes site,  No reference. 


Should i just adjust my order so it don't say the "S" hd,  But like this, Just RPB72-1621HD  Under 11,500 lbs.

Thanks Farmer.  Perfect..   I am so glad they called. Good crew there at tweety.
I must have clicked the wrong one 1621SHD and it was some sort of super heave special when it should have been 1621hd

I will call them back and get this moving again without the "S"

Thanks for all the help with this.. Been most helpfull.  Figured i should ask for input from you folks that have been there, before i tried to do this on my own.

Try some Goo Gone Adhesive Remover. You can buy it most anywhere.
