I'm looking at pulling my tank, it was in kind of rough shape anyway, and I
had seen that tank a while ago.  A night or two ago I thought I smelled gas
up by the tank at the front of the van.  It was hard to tell, but made me
think maybe I should go ahead and do this now since it was semi-planned
anyway.

GoWesty folks have a glowing description of this one:

Van Cafe has this--looks very similar, is this the same product?

Also, if anyone knows of a higher capacity option, I would be interested in
that as well

Thanks,
