Greetings from Colorado.
A buddy and I rode out to Pacific Beach in early May. Great ride.
I use this bag on my '00 Nomad:

It houses the amp for my stereo system, and the Ipod. Secured using the two middle windshield/trim bolts.
I have over 45K on my engine now, and it runs like a top - zero issues.
