Hey there.

I just replaced a bit of the flooring in our caravan because of sagging.
Now I was wondering if I can just attach another "boxed mild steel" with some angle brackets
to give the floor/plywood more support and prevent it from sagging again.
On of my mates told me I were not supposed to change anything related with the chassis.
Is that right? Otherwise I have to look for a different solution.

Here is a pictures of the flooring I replaced:


And a picture from the bottom.. where I would attach another boxed steel


Thanks for any advice

On a caravan of that vintage I should think that you would be able to make it stronger. A pity you have already fitted the new flooring, I would have added the extra bit whilst it was off and welded it in place. Even now you may still be able to mig weld it in providing you are quick and the panels are soaked in water. Run a bead down each side and leave the bottom horizontal faces open to allow for moisture to egress.
Just bolting or attaching a length along under the panel without affixing it to the existing structure would help to prevent the flooring flexing.

Drilling holes in the existing may tend to weaken the structure.

hi Sebastian. I would be inclined to drill out your new pop rivets, lift up the repair floor panel and mig in a piece of angle east to west between existing steel members. Keep a water saturated rag close to slap on between welds to prevent heat damage to timber. You may notice a bit of bowing of the steel work during quenching due to shrinkage on one side of welds but would not be of consequence. This would be a more professional and permanent way to carry out the job and give you more satisfaction in a job well done. These are great old vans. Good luck. :TU

Follow the advice given above, it has been done many times and the chance of a WOF guy picking it up if done professionally is slight.

Hey vansvilla & derb!

thanks for you advise. I will try to get that sorted, just need to find someone who ownes a mig welder and ask for a littl help :)
To remove the piece of ply is not a big deal - just a couple of minutes work - its probably becoming more awkward whenever I start putting in the
cabinets :)
Thanks again for the help.
