My requirements where: TT w/10K GVWR or less, 25-30' cabin length, 1 large slideout with couch/dinette, bunkhouse, outside shower, outside kitchen. We shopped several different brands that has similar floorplans but didn't like the interior decor and styling. Once my wife started looking at the Grand Design's it was pretty much a foregone conclusion we would buy one of them.
We ended up with the GD Imagine 2800BH. Great floorplan for us even as empty nesters. Can sleep 4 others as singles and alot more if you are small and friendly with your bedmate. Couch and dinette on slideout makes the inside feel huge when the slide is out. We can get to the bathroom, cabinets and fridge with the slide in from the rear door, unless we are parked in our storage building and too close to the walls where we can't drop the rear fixed step. In that case, I can open the slide about 16" and use the front bedroom door to access all of the trailer.
GD's Imagine 2500RL comes close to checking all your boxes in a 30'oal and the Imagine 2910BH does the same with an addition of the bunkhouse which you might not want. If you can deal without the walk through bathroom the 2600RB almost the same as ours but with out the bunks and the bath turned sideways.
