Rin,
Can you get some feedback from Alu-Cab in regards to real world issues with the wall kits for the Shadow Awn? I've set mine up once, so far, in my back yard to get familiar with it and it set up fine - no set up problems. But, that's not camping - it was calm and I wasn't staying in it so bugs, wind, & cold air weren't an issue - yet. In the camping I've done since installing the Shadow, have been 1 night and moving on to the next campsite, So setting up, taking down & putting away wall kit for a 1 night stay seemed unnecessary.
The main real world issue that I can see is no back wall or reasonable way to seal the vehicle side. Not only under the rig, but also where the awning attaches to the rig there's a gap allowing weather & bugs full access to occupants. From my previous experience in serious wind conditions (30+ mph), I can see it being near impossible to tie walls down to provide secure shelter. Was it Alu-Cab's intention for the wall kit to just provide privacy & sun protection? The screens on the windows are also a mystery...lol
Thanks for any insight you can provide!
