I haven't been here in a while but wanted to let you know about my latest update.
I recently loaned out my trailer to a friend of a friend, and wanted the trailer to be comfortable for her. I also have a seven-year-old daughter who loves gymnastics. I had just recently gotten her a gym mat for the garage (we don't have a basement) to do tumbling in for the winter.
It turns out that the gym mat fits perfectly in the teardrop. I already had a memory foam mattress in the teardrop, but if I sleep on my side, my hips and shoulders can sink through that pretty easily.
This is a 4'x8' mat, but the actual measurements are a little LESS than 4' width. I built my trailer on a 4x8 Harbor Freight utility trailer, so the actual interior dimensions are a little short of that. For length of the sleeping compartment, I designed it to be 6' (how tall I am, and more than long enough for my wife...)
Since the mattress is 8 foot long, it folds into four 2 foot sections. I put the gym mat in the trailer, but with the last 2' section folded up. It fit super-well and added a lot of padding!
Gym mats are durable, multipurpose, and foldable, so maybe not bad for a trailer at all! Anyways, it worked well in my experiment and I just wanted you all to know!
