We just bought a 2017 Imagine 2800BH. It is a very nice unit, and GD is selling a lot of them.
I considered the 2950 and looked at them very closely. The only downside with the double slides is that you cannot get into the galley.
The 2950 comes with a huge pantry so that is very nice as well.
I think the biggest negatives I have are the lack of 12 volt outlets, small gas bottles, the lack of HDMI from the entertainment center, and the rather thin mattresses.
I have not read many negative comments about these trailers and have only found one or two that had some serious complaints. My two problems are minor: one drawer not having a lock installed; the TV antenna dripping water, but it took a Louisiana deluge while driving 65 MPH to reveal it...not repeatable when stopped!
It makes one heck of a mancave.
