What does this mount to?

Some kind of support for a fold out bed or bunk bed.

Outside shower towel rack?

its a whatchamacallit for a doohickey. LOL

My guess is that it has nothing to do with your 5er but is something forgotten from some ladder or seat. I found a couple wood handles in our last 5er that were never explained - and didn't fit anywhere so .......
A couple RVs back, privately purchased, I found a survival knife, a 3 cell maglight and about ten bucks worth of change and bills. Had the PO done what he promised, I would have returned the knife and light but a couple hundred bucks later, I did his 'promised' work.

X2.

Perhaps it doesn't go to anything. An impish worker may have thrown it in there just for a prank. I had a coworker once who used to work in a farm machinery factory. They would occasionally throw some corn planter parts into the crate with a hay baler and just imagine people trying to put it together. In all seriousness, however, the dealer may know what it is if it is a usual Jayco item.

On edit: My Keystone Cougar has a rack very similar to this in the front compartment for extension cord/water hose/etc. I am certain this is what it is for.

Just for giggles....open up that sofa bed and check if both frame supports are there (side of frame rail towards end)


Otherwise......
Contact Jayco and inquire

Looks like about the right height to hook onto the bottom of the stairs for support. But then where does it go where you fold them up? Just a guess.....

No, it is light weight. I thought it may have been a stand for a tv but no tv's that small. Also thought it may have been for outside grill but again no.
