Hey guys, I'm hoping for some other good ideas, so post yours up.
Heres what I did in like 15 min..
I took a clear plastic box with snap on lid ( about 1.5 feet by 3 feet by 2 feet )
Cut some holes in the lower sides of it, with little notches for my bungie cord to fit in ( check link for pic )
Run the bungie through the 2 holes that i cut with a dremel in the box across the two D rings.
Then drilled a bunch of drain holes in the bottome of it ( 3/8 inch ) diameter.
I plan to leave it in there for the summer to throw my towells in on the way to the beach so they don't fly out of the bed...
and then throw wet suits and stuff in on the way home ( hence the drain holes )
cheap, useful, and quick!
