Definitely recommend having lots of help for decent size concrete jobs. You
really can't have too much manpower.  It's hard, heavy work.
The four pad thing might work but I would just bite the bullet and pour a
rectangle big enough for the van's footprint, assuming money was available
for such an undertaking.

Cheap and relatively easy to pour a  concrete slab that is level and can
support the weight of your Vanagon (4" is recommended but you can
probably go 3"  or even 2" if you have to, w/wire reinforcement or
rebar). Mostly all it takes is time and sweat. In fact you can make a
level work area for less than $100. Of course for that you aren't going
to get a full slab, just 4 small slabs, one for each tire. But you can
make sure they're level and fill in around them with 3/4 minus gravel ,
compacted well. Cover it all with visqueen before you pull on to it, and
you have a clean, dry, relatively dust free place to work that is
reasonably comfortable no less.
