Different trailers for different camping styles ... and that's something only you can determine. We're not the 'sit outside our trailer' all day type, therefore, when we looked at a 17' we felt it was just a bit cramped so we ordered a 19'. While we loved the 19', I felt we had sacrificed interior space for a queen bed (especially evident on very windy/rainy days when you're inside with two dogs). Our only hesitation on moving up was, for us, the awning and screen room which we used to 'extend' our living area; however, we felt the layout of the 21' would suit us better. Like the others, I would urge you to take the time to visit with other owners and spend some time in their trailers. That, alone, may make your decision easier.
We do not remember days, we remember moments.
