Re: Hi and seeking your advice
G'day Russell,
Welcome to the forum.
Here is a link to a manufacturer that make what you may be seeking.
http://www.explorex.com.au/These vans are OFF road and Dirt road models and are built with fully welded steel frames.
I have no interst in the company, I have seen the end results of their manufacturing and it is the best I have seen in the industry.
Cheers,
PeterM.
