Hey y'all.  I've got a parts van I'm going to leave in the carport of
my old house which I will rent out.  My goals for covering it are:
Make it look a bit more attractive than a dirty, rusty, 85 vanagon
with pieces missing; and keep people from possibly messing with
it.  The $200 Bus Depot one looks quite nice but may have more
features than I need.  Because the van is under a carport it will get
good airflow and little precipitation will hit it.  I really will not
need to get into it very often.  Maybe once a year?  Who knows for
sure.  I was wondering if I could make some kind of cover out of
those big blue or silver tarps, tied with ropes to keep it snug and
tidy.  Has anybody done this?  Would moisture be an issue?

Thanks!
Edward
