I too am deliberating. View/Navions hold their value, so I am finding much better deals for same years on Monaco Covina's and other producers (though not the Thor Citations).
The Thor Citation / Siesta looks better to me, more streamlined, I like the way the front cap looks more blended with the body, but doubt it gives more MPG (seems like it should, haven't heard).
Monaco Covina - can't find any first-hand experiences or forum posts yet, still looking.
Any advice appreciated.
Thanks!
