Four winds Seista

Just got a 2008 Fourwinds Siesta 2008 27 ft. Original owner had almost all manuals etc. only thing we're missing is the spec sheet that has all the height, width and especially the holding and fresh water tank capacities. He could only guess at the sizes as they always used full hookup sites. Sure would appreciate a pm with some info. Did go to Thor site and sent an email. Have not heard from them yet. Thanks in advance.
