If like me you has for years erected and USER tent with fixed groundsheet is the first structure of a shell that can be pulled in all directions a bit difficult one at that when the first building in the middle at work rears a thunderstorm. Allen who never USER a tent with inlay floor, I recommend a trial assembly in the garden in good weather. Now, after three appearances but I can only recommend the tent. Construction is now loose from the hand and also the first use of three weeks of life with really modest Weather convinced this tent. Despite several thunderstorms handed it every few days a bit to be more exciting. Insulation at night with temperatures plummeting well and absolutely no moisture inside.
