Smittybilt Overlander 2783. Love the tent, have spent about 20 nights camping in it and find it to be a solid tent with good construction and protection from the elements when in inside. Pic is from Big Bend National Park back in February. I removed the foam mattress pad and replaced with a full-size air mattress (takes about 30 seconds to inflate using my Ryobi 18v compressor). The air mattress makes a world of difference comfort-wise (rivals my bed at home). It deflates in about a minute as well. I typically pull the air release plug and then go "downstairs" to prepare coffee and breakfast. By the time I return, the mattress is completely aired-down and ready to be folded with the bedding at which point I can fold the tent closed.
Having said all that, I am looking at upgrading to the Smittybilt Overlander XL or the ROAM Vagabond. Reason being: exposure. The one limitation of the 2783 is that there is no real overhead/side coverage or privacy when entering and leaving the tent. The XL and Vagabond have "extended" coverings that provide more privacy and weather protection. Additionally, when using the attached annex room (which I will get), you can enter and leave the tent in complete protection/privacy so you can change clothes for instance which is my ultimate goal. My wife actually loves the tent, but doesn't like that she has no "privacy" when getting out and in.
