Lots of work on the QS10 this weekend - new power converter, lubed the axle, and installed straps on the PVC tube that stores the bunk end support posts.
I had read where a couple of QS owners had lost their storage tube on the highway. I had a pre-trip nightmare that I also lost my PVC tube on my way to a campsite, and then tried to support the bunkends with coolers. Definitely gotta secure that tube better.
The PVC tube is supported with 2 screws through the tube into the frame. I found some steel straps with a screw adjusted turnbuckle at the local hardware store that opened up to 7 in diameter. I figured that would be enough and it was ... barely. It took lots of attempts and all my strength to get the strap to catch and tighten around the PVC tube and the main frame beam down the center. But now I have 2 steel straps that will give me piece of mind and let me sleep.
It is an easy enhancement that I recommend. just get a long enough strap - at least 8 in diameter - or have more patience than me.
I had already did this modification on our camper and I used heavy duty zip ties.
