What's to say? Not so much in terms of images here. The exterior speaks for itself. Here are a few things to contemplate and consider.
Do we want wired or wireless running lights? Do we need entrance/egress ramp/s for the tail gate? Legs for the gate; stabilizers for the corners.
these items all depend on the application. We set these aside until we learn your use and need. Yes, we will paint. It's already fire retardant.
Would you like more awnings/rain guards over any of the windows? Would you like ribbon lights all 'round the eves to make it glow in color? .
How would you get the most out of the deck? B-B-Q on the gate or attached elsewhere? Think about it, and we'll figure it out and get to it.
How far and how often will it travel; or will it stay put? Maybe it's just fine the way it is; other than the painting... .
