I have lots of experience with adding a trunk to our 2005 RSTD. Went with a Wompus rack originally, really liked it. Used a less expensive Matasuko trunk first. Even then $350 would not be enough. Eventually installed a Harley Tour Pack on the Wompus rack loved it!! Recently wanted grab handles so I replaced the Wompus rack with RSV rails and RSV rack. My wife and grandson really like the grab bars. The extra cost is well worth it. That being said Patrolman46 purchased a modified RSTD backrest and aftermarket Harley looking trunk from another owner. I am impressed with the modified mount but cold weather has kept us from installing it. I am anxious to see it. I really like what I have but this other way might really be worth a look. Hope to install on Dan's bike this week. Sure willing to offer long distance help if needed.
