[VACList] Cover suggestions?

[Rob Super <rms@xxxxxxxxxx>]

Later this summer we'll need to move our '73 Safari (23') from rented 
enclosed storage to the driveway. I'm thinking about using a cover (as 
in "car cover"), but wonder what others' experience has been.

First question is: good or bad idea? The archives have some discussion 
of shed type fabric covers (i.e., those that look like tents) but 
nothing about those that simply drape over the 'stream. (Well, there is 
one mention of some bad experience with the latter, but I couldn't find 
the specifics.)

Second question is, has anyone found a mfr of such covers that fit 
Airstreams? Everything I've found is designed for boxier trailers. 
Maybe those work OK? Or not? Anyone w/experience?

Thanks,

Rob
