Thanks to those who responded to my propane leak question. 
I went by an RV parts store and picked up a regulator for
$27CDN or $18US. The procedure was fairly simple, and the
hissing under the van has ceased. 

One problem developed though. The pipes had to be bent
slightly, which seemed to have blocked a little flow. MY
advice to anyone would be to bend the pipes in a more
curved fashion, rather than almost kinking them like myself.
Also use some teflon tape. The Clerk was nice enough to
give me a one foot piece, which saved me from buying a whole role.

Thanks to the list,
Riley Kettner
