In our June 6, 2020 Manufacture Date Reflection 297RSTS under the bedroom mattress is a convenient storage area. However, we came across a gotcha regarding the LaVanture Black Nitrite Gas Springs. My wife (I coulda done it too!) opened the storage area fully extending the gas springs. They locked into the fully extended position and according to the LaVanture factory, they cannot be unlocked. DO NOT FULLY EXTEND. The only solution is to replace. LaVanture.com Part number LGPG6-200-40. $12.50 each with $10.00 shipping.
Now wouldn't it have been nice to have this pointed out in the customer delivery.
For those about to take delivery mention this to your dealer. For Grand Design a caution or warning sticker would be a great "do better". Don't know what other GD Models have this same product.

Happy 2021 Camping!
