Hi George & Sandy,
Just a word of caution regarding storage on the rear of your rv. That is a sensitive area wieght-wise. So be sure to get your rv weighed after it is fully loade to ensure that you haven't overloaded it. Handling can be aversely affected when the rear is overloaded on a motorhome (at least gas coaches). This causes the front to be 'unloaded' and makes things unsafe and uncomfortable.
If interested, come visit us in the iRV2 Chatters chat room. We're there just about every evening from about 8:30pm eastern until about 10:00pm. It's a great bunch of folks!
