Many years ago when I first started researching rvs I purchased the full package. I found much more information on forums such as here, IRV2, escapees, yahoo owners groups and fmca. I personally would rate their information slightly useful. There are many inconsistencies. For instance they rated one rv as a full time rv but a sister rv with the same exact build was not rated for full timing, very confusing.
If you are like me and most others who purchased you will probably buy it in the hopes of getting that one or two pieces of information that you think is unavailable anywhere else. Unfortunately you wont find any unique info. Keep reading and asking questions on forums and owners groups on yahoo.
