You'll love the Bullet, we've got the same floor plan and really like it . We've found it to be a very well built trailer and the second door was something we would not go without again. Congrats!
I just installed our Fantastic Fan vent cover last weekend. Looking forward to leaving my front windows cracked and the bathroom vent always open with my fan's thermostat set to come on when it gets hot inside while parked in the driveway. The combination of the fan and cover make for our best mod yet. Next up on the list is the lift-kit for the front queen bed that just came via Amazon.com.
These would be the top two items we'd tell Keystone to include right from the factory--a Fantastic Fan instead of the small push-button fan and a lift-kit for the queen bed to access the storage.
