d.polka, it isn't an RV group but Samaritan's Purse will be heading to the affected area Tues morning. You can go to their website www.samaritanspurse.org
and click on the link for volunteer under "ways to help" at the top right. There is a questionaire to complete about your skills. Just put on there you would like to volunteer with Gustav relief. SP is the international relief organization of Franklin Graham, the son of Billy Graham.
