Cheap, really cheap motorcycle luggage!

Take one of these: 

It's a 36 can cooler from Wal Mart. It was around 17.92. Add a couple of these:

Again, from Wal Mart for about 1.11 each. I used two. Then I found one of these in the garage:

I took a drill and drilled four holes in the bottom of the cooler, all the way through the rubberish bottom, through the nylon and through the plastic liner. Then you need to attach four of these:

to the four holes. I found a similar kit at Wal Mart in the camping section for around 3 or 4 dollars.

Once you attach the grommets, fit the straps through the holes and wrap them around the grab handles. Attach the straps so the clips are inside the bag. Get them tight. Then hook the bungee over the top and that bag is not going to move! At least, mine didn't and I hit speeds over 60 on the commute....couldn't be helped, you know?

This is the end product:

Not the prettiest luggage, but then again, it cost a grand total of less than $22 dollars.

It's big, too, probably more than enough room for a weekend trip. Tie the tent on and load up the bag and you're good to go!
