I'm looking for a tent for fly-out rafting. Have used the Cabelas Guide 6-man a couple of times. Enough room for 3 guys on cots with misc gear / dry bags tucked around inside. Question is... can I do the same for 2 guys in a 4-man? Cabelas website indicates the 4-man floor is 56 ft2, hexigon. If round it would have a diameter of about 8'. Seems a little tight for two 6'3" x 2'6" cots. Would want a small gap between cots so my cot does not get pushed around by the other one at night. Anybody with one of these tents used two cots? Thanks much.
