Shopping is fun! Pick your extremes on tolerance and focus in your comfort range both in age and class.
Pay attention to the models by year, not just the model name. Feature creep is alive and well in the RV industry, and within a few years a lower end model can be up there with the higher end models. For example, an Entegra Aspire today, is what an Entegra Anthem was back in 2013 in my opinion just because they pushed down so many features from the Cornerstone and Anthem each year into the Aspire. To get back to the value of the original Aspire you would have to jump down to a new Entegra Insignia entry model that they just introduced.
