You can add a teardrop trailer tent to your setup to expand your camping area. Some tents are specifically made for teardrop trailers so that they are attached to each other.
Other people simply use their own regular tents (that they already have) and set it up off to the side somewhere.
I have also seen people use a canopy to get similar results. The goal is to extend the area and protect yourself from the elements.
This way if it rains you're not stuck in your 4 x 8 teardrop trailer where you can't stand up!
6'2" tall, has windows, and seals completely shut. This tent might be
compatible with your current teardrop trailer--or one that you're
thinking of building/buying.
