These tents are very rare because they usually succumb to mold and mildew, even if well cared for. This tent is still in mint condition in 2015. 43 years old and better than anything made today.
Sturdy galvanized steel telescoping poles. Tent stands alone or could be tied down for long-term living. The ground cover could be placed on top as a rain fly, more for sun protection than rain. As long as you don’t touch the inside of the tent it won’t leak.
