I bought an Otter 650 Lodge (comfortable 3 man). Very good product, excellent sled, double layer fabric. I got mine end of season from Reeds for a great deal. If your always going with 1-2 other guys, don't go large like I did. Didn't take in to consideration all the gear weight. It's fine behind a sled but pulling by hand in snow or slush is a bear. Runner kit is a must!
