I looked at that floorplan in the dealers showroom several times.
For 370 lbs more and only 5' longer, you can get what I have for thousands less, and have more room, more privacy, more storage, and more sleeping.
The slide out bed will get cold. It's essentially just like a pop up with the cold right underneath bunk. You may need a mattress heater. It's like sleeping on the floor.
The back storage is nice for bikes but you then give up needed permanent storage for everything else. Put the bikes in the back of the truck or get a bike rack for the tongue of the trailer.
I'm not a fan of the laminated wall, floor, and ceiling construction that comes with it. I did like it but when I figured what I'd lose going to it, and the high cost that model demands with the wall construction that likes to delaminate, I chose Jay Flight models instead.
If the 370 lbs or 5' extra is a big deal, then by all means consider it. At least it's a true wall and not canvas, but I think Jayco has better 'bargains' in their line ups.
