I am planning to purchase a Momentum 399th to fulltime in and have a query about the double glazed windows vs the standard offering. Is there any data as to the advantages of one over the other? Specifically for noise insulating qualities. I touched base with Chad from Changing Lanes and he thinks it is less noisy but didn't have opportunity to do a side by side comparison. Any info you can provide will be helpful.

Just purchased the 320G. The amps in the Pantry are hot. Is there a way to turn them off when not in use.

Omg - I just viewed a video on you tube concerning a 2019 grand design roof that separated and it’s unbelievable that you market that crap as superior quality. You all should be held accountable for fraud
