ASA-To-ASA Dynamic-to-Static IPSEC Help

I have an ASA 5510 that has a static IP with a site-to-site IPSEC tunnel to an ASA 5505 with a static IP and that works great.

However, I know need to create another tunnel from the ASA 5510 to a different ASA 5505, but this 5505 has a dynamic IP.

I need specific steps on how I go about created the tunnel to the ASA 5505 that has the dynamic IP without messing up my other tunnel. I know I need to create a Dynamic Crypto Map, but that is all I am sure of.

Please help.

It would be nice if I could do this through ASDM, but if not CLI will work just fine.
