Welcome! We too upgraded from a pop-up to a TT, although our Roo is considerably smaller than yours.
You'll learn lots from this group. I have. Only downside is you may forget about leaving well enough alone and end up spending many hours and dollars on mods like I've done, thanks to the influence of these guys.
2016 Roo 21SS
2005 Ford Excursion-Sherman
