Thanks for the info guys.

I think I'm going to leave off all the "bling" and try to make it as cheap as possible, colourbond sides, straight (not drop) axles, steel chequer floor etc. If all goes well and I'm happy with it, then I might sell it to fund another one with the bling!!!!

Just got to finish the "plans" (used very loosely) and off to the welder and then start to order all the bits and pieces.

Cheers
Andrew
