I have the First Up Gazebo (with both walls and screen room) and the ARB 8' Awning. Both serve a purpose at camp, but neither do what I'd like.
When I have the RTT up(on the top of the trailer), the annex installed below (and to the rear of the trailer) gives some privacy below (I have the ARB Simpson III, so the ladder is inside the annex) ...which is very popular with the Mrs....because this allows the porta potty to be set up and left inside...vs. having to go outside at night to use it in the shower tent..she REALLY likes that. It also allows for the containers that are located inside the trailer, to be pulled and kept in a clean, dry area for access.
So after my last trip recently, I spent 4 nights "inside" the trailer, which was extremely comfortable...and so now I am toying with the idea of completely eliminating the RTT, which is a pita to set up because of the height of the trailer, and just using an "add-a-room" at the rear. A place to get dressed, set the potty up for her highness, and possibly use to eat/entertain in inclimate weather...or just stay away from the bugs.
The problem with the First Up, is the water sheds "towards" the trailer, and I don't believe that is the optimum set up in a monsoon....so in my mind, that leans me towards a gable peaked, or even dome type of "portable structure"...then trying to find one portable,lightweight, waterproof, with windows and doors is another story. I also would like to be able to customize the "skirt" that fits the trailer side/door opening, making it dry, and bug free.
One way to go is purchase separate frame fittings, and some aluminum tubing, and construct a deployable rigid frame. That will then have to covered with tent fabric, windows, etc.
Or the other option was to buy a premade structure, cut it in half, shorten the sidewalls, and have plenty of material to add doors, screens, etc, and a skirt against the trailer. With a gable roof structure, the water doesn't run towards the door. Here's an example...just picture it cut down to 10 x10'...I think with some ingenity and some minor sewing skills...you could up with a pretty cool structure, that would be durable.

I think we're both on the same page with the problem..the build is coming along great!
