I do believe oldcoot does have some very nice options as I have seen them in other posts. I have also used an add a room and they are nice. We are weekend campers and didn't use it all that often unless we were on a longer trip. But the ability to have the extra room to keep things dry and hidden was nice. Not sure about the stability for an all season long setup, but it will be great while it lasts. Make sure you anchor it well would be my suggestions. Consider what you will do during a bad wind storm.
