New to Grand Design

We are new to the Grand Design family. We have had 8 rvs and just purchased a 2022 Transcend 221RB. Any tips or secrets would be most helpful.

Just a little late to this group. However, we have a 2020 Transcend Xplor 221RB and have thoroughly enjoyed it. This was built before the pandemic and downfall of the quality that Grand Design experienced, and hopefully recovered from. We've experienced ONLY 2 issues, A) Foil ducting at the furnace torn and almost completely disconnected. This was a real PIA to repair due to VERY limited access & B) a lack of closing/sealing of the "Coroplast" to the underside, completely sealing all openings, i.e.; around the drain pipes & slide-out tracks, which made mouse access easy. We live in a rural area and store our TT on a concrete pad near the house with weeds & grass kept cut. This took a lot of persistence, & "Mouse Shield" insulating foam, to achieve a near perfect level of success. We wish you the best of luck with your trailer.
