Decided against Thor products in making our last purchase because of too many obvious quality issues when looking at units on dealer's lots. Currently have a 2013 Tiffin - prior to that our most recent units were Winnebago - both Winnebago and Itasca - and thought them both very good motor homes. Suggest you simply compare specs - the Hurricane is on the 18,000# Ford - the Tiffin on the 22,000# Ford. Tiffin has the fiberglass roof - Thor the TPO. Look further and you'll find Tiffin has many more standard features - some optional on the Thor but many not even available on the Thor.
