Greetings and welcome to the iRV2 forums!
Is your Thor a Class C or one of their smaller Class A? It will help us help you if we know what year and model of coach you have purchased. The "easy button" for this is to go to the User Control Panel here:
http://www.irv2.com/forums/usercp.php
In the left hand column you'll find "Setting and Options" and under that, "Edit Signature." You can enter up to 3 lines of text (unless you are a financial supporter or commercial user, then you get additional space). Most of us put the specifics of our RV there and maybe a witty quote or personal info like first names, pets, etc.
Your question about accessories should be a new thread in an appropriate forum - under the RV Forums heading there are subforums for Class A,B,C etc, general motor home discussion, and there are the Owners forums where things are organized by manufacturer name.
Take a few minutes to read some of the topics in each forum to get an idea of where might be best for your question. You'll get lots of help here.
Safe travels and good luck to you both.
