Welcome to the forum and congrats.
A couple of things to watch for
- Check all the interior LED light lens to make sure they are tight. We had one loose over the main TV and one over the bed. The light cans had to be changed.
- Check the water heater on electric then drain the tank refill it and check it again on LPG. Ours worked on LP but not electric
- Make sure the headboard is securely attached to the bedroom slide wall. Ours came loose on our way back from the Factory Service Center.
- Check the rear mud flaps to make sure they are secure and not rubbing on the rear tires
- Make sure the upper wipe seal for the kitchen slide wipes water off the slide as the slide is being closed. Ours will be going back for a second attempt at correcting this issue. Only after it rains, slide is retracted and then levelers are raised water will run off the top of the slide.
Those are a few of the things that we found with our 2020 Accolade 37TS.
