I have done a couple of minor additions of shelves in our Roo233S but I took the design that some one posted of the wooden tire chocks and tranlated them into aluminum.
So we made it to Elkhart and picked up our Roo 233S.So far we have been camping in it for 27 days/nights and have put close to 5000 miles on it. Best purchase that we have made. It fits our lifestyle perfectly.
