Just wanted your views on what body to chassis padding to use if any. I will be remounting my RV body back on a daihatsu f20 chassis in the next few weeks and now wandering if it would be better off without any. When I removed it there was 1 1/2" rubber belting laid across the top of the chassis for the body to sit on, the problem with that was moisture had been trapped under it causing rusting of the chassis, the top of chassis also being flat not helping matters
I don't want this to happen again as it means removing the body to gain access to it. So is it common practice to use some form of cushioning or not? Cheers, Brian.

Not sure what the standard set up is for this. My SS didn't have anything between the chassis and body. But I figured some kind of padding would be a good idea so I've put rubber strips on my chassis in preparation for the body going back on, I did buff down and re paint the chassis before I did this so I would hope it. Should last some time

I did phone the factory when building my RV to check weather to put in some sort of foam/rubber and was told most people didn't fit any sort of padding between the body and chassis. It wasn't recommended as it was thought that it would cause the damp to sit in between the two items,
Like Maverick says if prepare the chassis top well and give it a good coat of paint it should be alright for a good few years, even if you decide to refit some rubber strips.

I also used silicon between the chassis and the strips, one reason for using it was basically as glue to hold it in place, the other was to hopefully prevent moisture getting in brett

I personally work with something different, I apply a layer of liquid latex to the chassis contact area, you can buy it anywhere and is easily to apply. Firstly, with body unbolted and lifted a little above the chassis.
2nd step, every 60 cm or so I put hard rubber strips of 2mm thick across the chassis, they should have one end outside the chassis rails, 1cm over is enough. Next,I apply a layer of flexible latex silicone that has no acetic acid and is compressible by 60%.
Replace the body on the chassis and tighten the bolts lightly, the silicone then distributes evenly nicely. Next day I remove the rubber strips and then fill in with latex where the strip were removed and then tighten all the bolts.
You have a now perfect rubber gasket of approximately 1.5 mm thick which is neatly compressed. Big advantage of the latex is it adheres well to the chassis, but if the body is ever coming back off, with a little power the latex comes nicely away from the chassis without having your whole chassis scrapped (?), and you can use the same gasket again and again.
Difficult to translate in English, but I hope it is understandable. (I hope I have understood what you meant and cleared it up, I know what you mean Luc hmmmm[1]Peter)
