I have the LightHeart SoLong 6 with awning and two doors. Looked at, bought and tried the solo, but was too cramped for me. I also didn't like the wasted space in the pointed ends.
Only problem in FL summer is condensation. Seam sealed it myself with the recommended 1/2 - 1/2 mineral spirits and 100% silicone caulking and have had NO leaks.
I'm 220 #, 6'2". SoLong 6 fits great
