Some of the amenities. A physical door on the bunkhouse vs curtains, power jacks, third slide, 21' awning with lighting, trundle under the couch in the bh, etc. Also the price, we got a very good deal and the solaire dealer is only 15-20 minutes from our house. The price and weight were huge factors. Also the looks with the optional front cap. We spent 2 months and many hours looking at brands, options, weights, and locations of dealers (including a couple of multi hour drives to look at other brands). The Solaire turned out to meet all of our needs, and most of our "wants" in one package while still meeting our budget. We are excited to get out this spring.
