In this day in age, it seems that our users are accustomed to scrolling. Sure, it's good to have your main points "above the fold", or in other words, above the point in the browser window that the users can immediately see without having to use the scroll bar to access content that appears lower on the screen.
I've seen websites that end up doing things like this.
But, when evaluating this, it seems silly. In this design, it would have made more sense to simply leave off the navigation tiles at the top, and all the "Back to top" links.
This specific design begs the question...
Is there research that has given clue to an acceptable range at which a scroll is totally viable? I could understand if the RV descriptions were larger, then maybe it would warrant a top side navigation such as this, but how much larger?
