I fish out of the lodge and the resort models so I can’t help you with first hand reviews on the cabin but as far as quality and durability goes, since they’re all built using the same materials, I can definitely chime in on that. You will have to sit in one and get a feel for if it meets your expectations for room as that comes down to personal preference.
When a guy buys an Otter he’s throwing money down on a ice house that is built to be the “best of the best” when it comes to materials used. 900 denier outer shell, roto molded tubs… thick square tube framing all makes for the toughest, most durable house I’ve fished out of. In 5 years of filming ice shows out of the Otters I’ve never once had any type of failure and I’ll be the first to admit we’re very hard on the houses as they function as our “pack mules” for all our gear. We cover a lot of lake, portage and trail miles and when we have a full load of equipment we’re dragging 200 – 250 lbs of gear in one resort. We’re carting around a 12′ crane + 75 lbs of ballast weight, light stands, lighting equipment, multiple cameras and film gear plus all the “normal” fishing gear that goes with a guy out on the ice. The hitch is bullet-proof and the tubs and frames never show much for wear at the end of the season when I turn them over and the thick outer canvas shell wears like iron. I know most competitors have stopped listing the denier rating of their houses because most are under 500 – 600 denier now to cut costs but you’ll be able to spot that difference by feel if you can get your hands on various models for comparison.
Two years ago I had 860+ lake, trail and portage miles on an otter resort that I was able to track using my odometer on the designated sled that pulled that particular house. I sold that house to a guy here on IDO. When he came to pick it up he commented on how it looked basically new.
If you plan to fish hard and often or just want to have a house that’s going to last a long, long time… I couldn’t recommend the Otter more highly.
