I am having difficulty with deploying VLAN's. I will add a VLAN to a trunk port on both sides using the configuration command "switchport trunk allowed vlan add ...." and I can see that it has been added to the trunk, but when I do a "show vlan" its not there at the switch I want it on. I even create a dummy vlan on the server to up the revision and force a database send out but still nothing. Are there other things to look for when adding a VLAN to a trunk and deploying to an access switch?
The switchport trunk allowed vlan ... command does not add a vlan to a switch, it adds a vlan to a trunk link.
You need to either use VTP and have a VTP server where you create vlans and then VTP clients that update their vlan database based on that or you use VTP transparent and manually add the vlan to each switch.

I know I should’ve put more information. These VLAN’s are already in existence on our network and are in production and are configuration is four or five VTP domains each having a server on distribution switches and clients are the access switches. Above the distribution switches is a core switch. VLAN’s are created on the core and distribution switches. Sometimes a Diylan Hass to be added to another VTP domain and then propagated down to the clients and that’s where I have my problem.
I know it can happen that people are posting at same time you sometimes see same response from multiple users so maybe that is case here but you referred to the other answers in your post so I assumed you had seen them already.
No problem.
