Reserve sticker or not, you there are easily identifiable differences between the reserves and the non-reserves. That's what really matters.
1) Do you have solid counter tops?
2) Do you have Power Stab Jacks?
3) Do you have an electric fireplace?
If yes, yes, and yes..you have a Reserve.
Yes, stab jacks were an option for non-reserve models, but the other features are not in any way upgradeable from the factory.
The notion that it is a somehow an reject or seconds from the factory is a stretch. These units roll off assembly line with issues. Its a cold hard fact of RV ownership unfortunately. If you want fit and finish, I think you are going to be hard pressed to find an ultralite travel trailer that is that well crafted. These trailers are mass assembled and remember, they take a beating going down the road. My shower on my new 2016 was water tight. 1000 miles later, I have a leaking door.
