Welcome and congratulations. I have 2012 ZT 260 BH love it.
Since 2015...Serves us very well, Iím a nut about maintenance, however I did have serious damage from a very minor unknown leak that probably was happening since new gone undetected. The two rear vertical corners the caulk looked good but through the physics of surface tension, water adhesion water seeped in for four years soaking the insulation and the wet soggy insulation rotted some floor joists and rim joist. I rebuilt it all from the bottom, removed enclosed belly coroplast, black tank, plumbing etc. rebuilding better than new. Resealed the corners with Dicor product made just for corners similar to but lighter than Eternabond then new re install corners and caulked.
I also re enforce the fresh water tank supports, because they failed, and the tank dropped. Also super mouseproofed entire camper, making it impenetrable to mice.All good now.0
