Bad-ass. I really like the chopped back, that opens up all kinds of possibilities.
I've got a '73 Dodge Tradesman van I'm using for similar purposes. Same engine and it looks like the same chassis.
For a good sealing tape, check out Permabond. It's used on RV roofs and supposedly lasts for 10 years when exposed to the elements. Not cheap but it's worked great for me.
