Just for the record, Steve gave me a great deal and I couldn't be more pleased.
Probably paid 40% of a new one. Like someone else said, the "extras" are pricy. Steve had numerous extras, probably $1,000 worth.
It's 16' long with the 12' tent. I haven't used it. But I set it up and left it when we were experiencing 30-40 mph winds, no issues. And when it was 90 outside, it was cooler in the tent with the windows open than it was outside.
I loaded both my side by side and my wife's Polaris 500 quad on it and towed it around the property. Pulls like a dream.
Initially my plan was to use it on 2 antelope hunts this year and use my wall tent for the Colorado elk hunt. But I'm leaning towards using it on that too. I get that there isn't much between you and the outside during cold weather. But I think a combination of 2 Mr. Heaters, 1 Mr. Heater and 1 Lil Buddy, or just one Mr. Heater, should keep it warm enough.
We'll see. I sleep in a nylon "Outback lodge" on a cot, with a lil buddy, in January chukar hunting. At least I won't have to removed tent stakes frozen into the ground anymore.
