Hi Morsecodeham, Yeah the 2006 also has only one axle. The other difference is the way the bed is, yours turns into a couch mine doesn't. It has gaucho seating instead of a booth and table. I have only used it for one summer and only noticed the sewer hookup a little low to the ground when backing up on some sites that have a little incline.
