We have the side tent from Camp Inn. (Please excuse the poor picture of it.)
Pros:
-attaches to the teardrop
-solves the "where to put shoes question"
-allows teardrop door to be open for more air circulation
-large enough to use as a change room and potty room
-well made
Cons:
-expensive
-smaller and shorter than some
-won't fit some teardrops
-have to buy your own Texas A&M string lights for it
Take care,
Tom
