Traded my 2003 RT for an 08 GT, and just can't see the top case priced at nearly $900.00. I had the top case on my RT, and it was great used it every year for the rally always met my expectations. I know about the givi options, but this time I think I'm leaning toward a large dry bag. I have been looking at the Sea to Summit line, and was wondering if anyone has had any expieriences with them. I'm Looking at the E-vac or the Big River dry bag.
