I bought this to put my tractor in and have ended up using it for my new Toyota Tundra truck instead. Unit has been up for about 7 yrs and has done well. Several small holes in it from where birds have gotten in and trying to get out. Done well in upper Tennessee area with cold winters and hot summers. Just moved unit from original site to another and it was not very hard.  I am 68 yrs old and only had to have help pulling cover over center area.  if need another shelter will buy again.
