1) No , tight even for a single gun hunter .
2) I hunted out of the same Outhouse for 4 years without noticeable fading or other loss of quality such as fraying of edges , broken zips , etc.
3)All tent blinds have their positives and negatives , only you can decide them . If you bowhunt exclude the Outhouse and go for the Doghouse , Blockhouse , Penthouse , etc.
