Chris - Sorry to hear about your wife - hope all goes well there.
Now about that shell - no excuses, Just because it is at the beginning of it's resto journey, don't think is is not good enough to show us. There is about a dozen van restos in various stages of completion around the country so we're keen to have a bo peep. Post up some pics so we can see what you have in front of you. Plenty of free advice and assistance here mate. Someone might spot something you hadn't yout thought off and point you in the right direction to avoid problems later.
About the Spit [rotisserie], not too many have done one on a van here in Oz but we had a discusion on this topic a few months back - have a read in this topic

I found a site with some pics of an english Traveller on a spit at this site at the time.

And the trolly idea has been worked by JAM into a "how to make one" on his web site at
http://www.justanothermini.tk/ [in the technical section]. he did offer it for sale some time back, not sure if is still available, give him a yell.
I have to make one for Donkey as well, but I'm doing all the mechanicals and interior custom fit out first, when I get all that just right - then he gets completely stripped down for a full bare metal paint job.
