I can't really help you with specific answer but there are members of this forum that have built their own and should be able to help.
Check out this link on Roadtrek's site: http://www.roadtrek.com/prodpro.aspx
It is the Production Process
of How are Roadtreks Made
. It shows their newer models but it should be of some help.
Re: the Dodge van - there are complaints on forums about the handling of some vans. Basically, a good highway test drive should answer that question for you. My 1998 is easy to drive.
Your project will be a lot of work but also fun. Are you planning to camp with 4 people in the van? It probably would be a bit tight.
Also, maybe consider taking the Roadtrek factory tour in Kitchener.
