It does look like a pop rivet.
I can't see it clearly but I'd the thing in the middle a type of screw head.
That might move things up and down, maybe.

The silver thing hanging down through the hole feels like its around 45mm long. Hard to see clearly but it looks like the small end is sheared off. The black rubber ring seems to have absorbed the adjustment bolt.

Very hard to tell from the photo and although I may be wrong it looks like each photo is of a different post, not that it matters. From what I can make out there looks like a threaded rod towards the bottom of the first picture which may be the adjustment. To access to you will need to take the bottom cover plate off that I can see is held on by 1 screw and that may reveal more.

Good luck and hope all goes well for your wife.

Tim they are the same post, one from the front and the other from underneath. I took that single screw out (threaded) thinking I may be able to remove that plate but it didnt budge.

There seems to be a number of sites that show parts breakdowns of these Happijac products. eg...

Perhaps search for the model you have to locate the required breakdown view.

Thank you for the clarification and I can see clearly now as previously it looked like the one photo was taken from outside. No idea why I thought that confuse but it was dark when I looked at it. Have you done a comparison with the base of other posts?

The only other thing I found that appears a comprehensive way of adjusting it is on a US forum but you need to be a member to be able to view it. I'm in the UK at the moment and it won't let me register to view it. Probably the same for in Australia but give it a try. If it doesn't work for you I will see if I can find someone in the US to register and send me the PDF file.

That would be great Tim. Ive googled the bejesus out of it and still have no clue. I tried to contact Lippert who bought Happijac without success.

Hi Ineedabiggerboat, sorry to say I had a friend in the US join that motor home forum and try and open the link. It looks like management have modified it and it now redirects you to a list of user manuals and and tips but I have gone through it numerous times without any luck.

When he is awake again I will get his login details and keep trying.

Meanwhile are you still able to raise and lower the bed?

Good luck

Tim

Thanks Tim. Up and down once a day. I need it to last three more weeks. (-:
