Right guys this is my first post on here and i need a little bit of help, i got hold of a caravan chassis of a friend for free (bargain!) and i'm turning it into a car transporter. It'll be carrying a stripped out mk5 fiesta about 900kg. I've got a couple of pictures of it, anything that isn't red is what i've welded in.

I've boarded it with 9mm plywood and the wheels of the fiesta sit exactly on the two bars that run down either side on the first picture.

I still need to 'beef' it up as my dad says it flex's when he stands on the rear. Any ideas of what i could do to make it stronger? I also need to strengthen the A frame. Any help much appreciated!
