Welcome to the forum from Ontario, Canada and congratulations on your new Roo.
You'll find lots of hybrid owners who also moved from a popup. We went from a 2 man tent to a larger tent to a Coleman popup to our previous Roo and now we have a 29' TT.
While you're awaiting the arrival of your new Roo, take some time to search the forum for answers to all your questions. If you can't find the answer in a search, members here will be more than helpful.
I'm sure you'll have lots more questions when you finally get your Roo but before you sign the paperwork, insist on a very thorough PDI walk through. Make sure everything works and that they show you how it works and how to winterize it. The library section of the forum has a great PDI checklist to take with you.
