I have been tent camping for 40 years, decided to do some winter camping, looked at all of the higher end canvas units. Decided on the Springbar Classic Jack 140 w/ the hot tent zip in panel. Absolutely the right choice! No need to cobble a stove jack into it, the quality is second to no other manufacturer. The only down side is build location, personal issue only, the unit I received is perfect in construction. The service is flawless and I highly recommend you buy on quality, support and the ready to use value, not price. Side note, the Winnerwell stove kits that Springbar associates with are flawless, well designed and the fit and finish are beautiful. Well done Springbar, well done.
