I would offer that a fastener failure observed on my bought new 2026 Intech OVR Navigate camper sheds light on what happened to your Intech camper.
After the initial tow home from the at-dealer purchase, the electric brake lanyard pull switch assembly came off in my hand as I stowed the trailer.
The head of the power tool driven self-drilling screw had separated from the shank, at zero force imposed on it, from just the wiggling during lanyard stow.. The shank, however, was stuck fast and not easily removed from the aluminum frame. I opted to drill a new pilot hole nearby and secure the lanyard pull switch body back onto the frame using a skirted metal roofing screw, installed by hand via ratchet wrench and socket, so as to not tighten it to where the lanyard switch was hard pinned, or the head of the screw wrung off.
Looking at your photos, two screws that were originally secured that piece to the frame have their heads separated. The shanks are there, as "stuck studs", same as what I saw on the OVR.
Also, there is a visible contact print where that hose support piece was originally in firm contact with the frame before the two fasteners separated.
The screws did not pull out. You don't need a spacer. You experienced a separation of the head from the shank at two fasteners that were overstressed at the factory by the driver tool that installed them. One of the heads still has a bit of shank remnant on it, so it stayed in place at the surface of the piece that it no longer secures.
Intech is inadvertently overstressing some of the self drilling screws during install/build. Probably a chinese low strength screw supply choice problem.
They did not yet get told about the failure on my OVR, as I regarded it as a one-off. They don't know about your overstressed fastener faiure either, so unfortunately, more of us customers will experience the after effects of random factory-overstressed self drilling fasteners by having some fail.
I had a problem with the stairs and Intec generated a service bulletin and new part in less than 30 days after I asked for a fix. We owners should let the factory know about these fastener failures.
