The replacement stereo I would recommend for your 2017 Thor Synergy TT24 Motorhome is the Jensen RV Stereo - Double DIN - AUX/USB, Bluetooth, jControl - 12V # JWM60A. The # JWM60A is the updated model of the JWM6A, they use the same pigtail so there won't be any rewiring needed. view full answer...
For a 87" flange to flange slide-out you will want to use the Solera RV Slide-Out Awning # LCV000168106. This topper has a fabric length of 91" giving you 2" of coverage past the flanges of your slide out to prevent debris from blowing under the cover. view full answer...
For your 2019 Thor Synergy 24SK motorhome, the Sprinter frame and front end on your motorhome will allow you to use rain guards. You will want the WeatherTech # WT64AV for the rain guards, but we do not have a bug shield compatible with your motorhome. view full answer...
